AI image generation for beginners: your first image, step by step

You don't need design skills, software or a graphics card to make good AI images. Here is where to start, from your first prompt to your first post.

Published 2026-10-26 by Cat Claw, the UK's create-and-distribute AI studio. About a 16 minute read.

The short version

• AI image generation turns a written prompt into an original picture using a text-to-image model. No design skills, software or graphics card are needed, only a browser and clear words.
• A good beginner prompt has 5 parts: subject, style, mood, lighting and composition. Lead with the subject and change 1 part at a time between renders.
• Choose the aspect ratio before you generate: 9:16 for Stories, Reels and TikTok, 16:9 for YouTube thumbnails, and 4:5 or 1:1 for Instagram and LinkedIn feeds.
• On Cat Claw AI, sign-up is free with no card, an image render starts at 3 credits, and the smallest credit pack is 100 credits for £4.99, enough for 33 renders at that price.
• Every Cat Claw render shows its credit price before you confirm, and a render that fails is refunded automatically.
• Under the Cat Claw Terms you own your outputs and can use them commercially, but copyright in AI-generated work is still unsettled in the UK and elsewhere.
• Finished images can be posted to around 15 social platforms from the Cat Claw studio through Puurfect Post, and posting itself costs no credits.

AI image generation is the process of turning a written description, called a prompt, into a new picture using a text-to-image model. You describe the subject, style and mood, and the model builds an original image to match in under a minute. It needs no drawing skills, no design software and no camera, just clear words.

This guide is for complete beginners: what AI image generation is, what you need, how to make your first image, which tool to pick, how to share it and what you can do with it. It is written by Cat Claw AI, a UK-based AI creative studio, and every product detail in it has been checked against the studio as it works today. If you already make AI images and want the full production workflow, our guide to creating and publishing AI-generated images goes further.

What is AI image generation and how does it work?

Quick answer. AI image generation is creating a new picture from a text description. A text-to-image model has learned, from huge numbers of images paired with captions, how words relate to what things look like. When you type a prompt it doesn't search for an existing picture. It builds a new one, usually by starting from random visual noise and refining it until it matches your words.

The most common type of model today is a diffusion model. Think of a sculptor working in reverse: it starts with static, like an untuned TV, and removes a little noise at each step, guided by your prompt, until a clear image is left. Subject and composition settle first, then light, texture and style.

The practical lesson: the model fills every gap in your prompt with an average. Say very little and you get something generic. Say exactly what you mean and you get something that looks chosen.

Does AI copy existing images?

Not in the sense of cutting and pasting. The model generates new pixels from patterns it learned in training, so each render is a new image. It can still imitate familiar characters and logos if you ask, which can infringe someone's rights, so describe your own idea instead.

What can a beginner realistically make?

More than most people expect on day 1, including:

• Social posts, carousels and Story backgrounds.
• YouTube thumbnails, blog headers and newsletter graphics.
• Product mockups and lifestyle scenes for a small shop.
• Illustrations, patterns and wall art.
• Mood boards and concept art for a bigger project.

The hard jobs for any engine are small readable text, hands, and keeping the same face or product identical across a series. Engine choice matters most for these.

What do you need to start making AI images?

Quick answer. You need a device with a web browser, an account on an AI image platform and an idea. You don't need design skills, design software, a powerful computer or a graphics card, because the image is rendered on the platform's servers, not on your machine.

Do you need design skills to use AI image tools?

No. The skill that matters is describing what you see in your head precisely: the subject, the look, the light and the framing. That's closer to writing a good brief than to drawing. Design knowledge helps later, when you're choosing between versions and finishing an image, but you don't need it to start.

If a blank prompt box feels daunting, Cat Claw's Studio Copilot lets you describe what you want in plain words, or speak it into the mic, and in Smart mode it picks a suitable model for you. In Ask mode it checks with you before it spends any credits, which is a sensible setting while you learn.

Is AI image generation free?

Signing up is free on most platforms, but rendering usually isn't, because every image uses real computing power. Some tools include a small free allowance; others, including Cat Claw, are pay as you go from the first render.

On Cat Claw AI the numbers are:

• Sign-up is free and no card is needed. You can browse the studio, the guides and the prompt marketplace without paying.
• New accounts start with 0 credits, so you'll need a pack or a plan before your first render.
• The smallest credit pack is 100 credits for £4.99. Pack credits last 12 months.
• A Seedream image render costs 3 credits, the lowest price of any action in the studio, so that first pack covers 33 renders.
• Monthly plans start at £14.99 for 350 credits. Plan credits refresh each month and don't roll over.
• Every tool shows its credit price before you confirm, and a render that fails is refunded automatically.

How do you make your first AI image? A step-by-step walkthrough

Your first AI image takes a few minutes, and most of that is writing the prompt. The walkthrough uses Cat Claw's image studio, but the same order works on any platform.

1. Decide where the image will live. Pick 1 destination before anything else: an Instagram post, a YouTube thumbnail, a blog header. The destination decides the shape, and the shape decides how you describe the framing.
2. Sign up and add credits. Create a free account at catclaw.ai with an email address or Google. Add the smallest pack or a plan when you're ready to render.
3. Open the image studio and choose Seedream. Seedream is a sound first engine. It handles photorealistic and artistic images, renders text inside the image, and costs 3 credits a render.
4. Set the aspect ratio. Seedream offers 1:1, 16:9, 9:16, 4:3 and 3:4. Choose 9:16 for a Story, Reel or TikTok, 16:9 for a thumbnail, and 1:1 or 3:4 for a feed post. Choosing first stops you cropping off the important part later.
5. Write a 5-part prompt. Describe the subject, style, mood, lighting and composition, in that order, with a short phrase for each. The next section shows exactly how.
6. Try the prompt optimiser if you're stuck. Seedream has an optional prompt optimiser with default, photographic and artistic styles. Comparing its version with yours shows which details matter.
7. Render, review and change 1 thing. Check the credit price, confirm and wait, usually under a minute. If it misses, change the 1 part of the prompt that was wrong and run it again. Most good images take 3 to 6 attempts.
8. Save it or post it. Download the finished file, which carries no watermark, or send it straight to your connected social accounts through Puurfect Post without downloading it first.

How do you write a good AI image prompt?

Quick answer. Describe 5 things in this order: the subject, with 2 or 3 concrete details; the style or medium; the mood; the lighting; and the composition, meaning the framing and angle. Use specific, visual words, keep each part short, and change 1 part at a time between renders.

Think of a prompt as a brief for a photographer or illustrator who can't ask you questions. 'A dog' gets you a generic dog. 'A golden retriever sitting on a wet pavement outside a London bakery, morning drizzle, soft grey light, photographed at eye level' gets you the picture you had in mind.

Put together, the strong column reads as 1 prompt: 'A small corner cafe with a striped awning, 2 people at a window table with laptops. Watercolour illustration with loose ink lines. Calm and cosy, warm autumn colours. Late afternoon sun through the window, long soft shadows. Street-level view from across the road, cafe centred.' That's 45 words, and every one of them does a job. Set the shape with the aspect ratio selector rather than in the prompt.

A beginner prompt template you can copy

Template. [Subject, with 2 or 3 details]. [Style or medium]. [Mood and colours]. [Lighting]. [Framing and angle].

Fill each bracket with a short phrase and leave out any you don't need yet. A prompt with only a subject and a style is a fine first attempt. Add the other 3 parts as you see how the model fills the gaps you left.

Words that don't help

• Quality stacking. 'Masterpiece, 8K, ultra-detailed, award-winning' says nothing about the picture. Describe the light and the angle instead.
• Contradictions. 'Minimalist and highly detailed' averages out to neither. Pick one.
• Famous names. Naming a living artist, a film character or a brand invites a lookalike you may not be allowed to use. Describe the qualities you like instead.

When you want to go further, the full production guide has a worked 60-word prompt and a studio tip on writing light.

Which AI image tool should a beginner choose?

Quick answer. Choose a tool that shows the price before each render, lets you pick the aspect ratio, gives clear commercial-use terms and doesn't charge for failed renders. Then pick by what you'll do with the images: if you'll post them, a tool that also publishes saves the most time.

There are good options at every level. General assistants such as ChatGPT can make images inside a conversation, Adobe Firefly sits inside the Adobe apps, and Midjourney is popular for stylised art. Studios such as Cat Claw put several engines, editing and publishing in one account. Judge any of them against this checklist.

• Price shown up front. You should know what a render costs before you press the button.
• Fair failures. A render that errors shouldn't cost you.
• Aspect ratio control. You need square, portrait and landscape at minimum, and ideally 9:16 and 16:9.
• Clear rights. The terms should say who owns the output and whether you can use it commercially.
• Room to grow. Editing, reference images and publishing matter once you're past your first week.

Inside Cat Claw, the image engines line up like this for a beginner.

Which aspect ratio should you use for each platform?

Quick answer. Use 9:16 for Instagram Stories and Reels, TikTok and YouTube Shorts; 16:9 for YouTube thumbnails; 4:5 or 1:1 for Instagram and LinkedIn feed posts; and 2:3 for Pinterest. Set the ratio before you generate, so nothing important gets cropped.

If your engine doesn't offer the exact ratio, generate at the nearest one and crop. Seedream has no 4:5 option, so for an Instagram feed post, render at 3:4 and trim a little from the top or bottom.

How do you share AI images to several platforms at once?

Use a distribution tool rather than uploading to each app by hand: connect your accounts once, then post or schedule in 1 action. In Cat Claw this runs through Puurfect Post, which sends finished images to around 15 social platforms, including Instagram, TikTok, YouTube, Facebook, LinkedIn and X, from the studio. Posting itself costs no credits, and nothing is posted to your accounts without your go-ahead.

A detail from the Cat Claw studio. Send a 9:16 image to Instagram from Cat Claw and it's set up as a Story by default, not a feed post, because the feed can't hold a full-height vertical image. You can still change it before you post. It saves you the rejected upload that puts many beginners off posting.

How do you keep a consistent look across your images?

Write your look down once and reuse it. Pick a style line, a mood and a colour palette, and paste the same words into every prompt, changing only the subject. Over time your audience recognises your images before they see your name.

Words only go so far for faces and products. For those, use reference images: Seedream 5.0 Pro accepts up to 10, so you can hold a person, a product or a palette steady across a series. Cat Claw's Kitten Shot goes a step further. Upload 1 photo and it produces a reference board, such as a character sheet, a turnaround or a product board, that you can use as the reference for everything after.

What are the most common beginner mistakes with AI images?

Most beginner frustration comes from 4 habits, and all of them are quick to fix.

• Writing vague prompts. With little to go on, the model fills the gaps with an average. Add the setting, the light, the style and the mood, a short phrase each.
• Ignoring the aspect ratio. Generating a square image and cropping it to 9:16 later cuts off the top and bottom of the scene. Choose the shape first.
• Rewriting everything after 1 miss. If the light is wrong, change the lighting line and keep the rest. You'll learn what each phrase does, and spend fewer credits.
• Asking for 3 pictures in 1. A product shot, a lifestyle scene and a headline are separate images, or 1 image plus an edit.

Expect your first few renders to miss, and give each idea 3 to 6 attempts before you judge it. It doesn't need 9 lives, but it deserves more than 1.

Can you make money from AI images as a beginner?

Quick answer. Yes, though rarely straight away. Most beginners start by using AI images in their own content or business, then sell prompts, print-on-demand products and digital downloads, and later take on paid client work. What sells is a consistent style and a real use, not a single lucky render.

• Use them in your own business. Blog headers, product mockups, ad images and newsletter graphics pay back first, because they save you money straight away.
• Sell the prompt. On the Cat Claw marketplace every prompt sells for £1.99 and the seller earns 20 credits per sale. Bundles of 3 to 8 prompts sell for £4.99 and earn the seller 40 credits. Sellers are paid in credits, not cash.
• Sell prints and downloads. Print-on-demand services put artwork on posters and mugs with no stock to hold, and wall art and template packs sell as digital files.
• Take on client work. Once your results are consistent, mood boards, social sets and ad variants are paid work in their own right.

On ownership, read the terms of the tool you use. Under the Cat Claw Terms you own your outputs, to the extent ownership can exist in them, and you can use them commercially. The legal picture is less settled. The UK's Copyright, Designs and Patents Act 1988 has a provision for computer-generated works, while the US Copyright Office has said that material generated purely by AI, without human creative input, can't be registered. Copyright in AI-generated material is unsettled in the UK and elsewhere. This is general information, not legal advice.

In advertising, show products as they really are and follow the ASA and CAP codes and each platform's AI disclosure rules.

Frequently asked questions

What is AI image generation in simple terms?

AI image generation is typing a description and getting a new picture back. A text-to-image model has learned how words relate to what things look like, so it can build an original image that matches your prompt, usually in under a minute. You don't need drawing skills, design software or a powerful computer, because the image is made on the platform's servers.

Do I need design skills to make AI images?

No. You describe the image in words instead of drawing it, so the skill that matters is being specific about the subject, style, mood, lighting and framing. A usable result in your first session is realistic. Design experience helps when you're choosing between versions and finishing an image, but you don't need it to start.

Can I make AI images for free?

You can sign up to most platforms for free, but rendering usually costs credits or a subscription because each image uses real computing power. On Cat Claw AI, sign-up is free with no card, new accounts start with 0 credits, and the smallest pack is 100 credits for £4.99. A Seedream image costs 3 credits, so that pack covers 33 renders.

How long does it take to make an AI image?

A single render usually takes under a minute. Your first good image will take longer, often 3 to 6 attempts while you adjust the prompt, so allow 10 to 20 minutes for it. After that, with a saved style line, a new image for a post takes a few minutes.

Can I use AI-generated images commercially?

Usually, but it depends on the tool's terms. Under the Cat Claw Terms you own your outputs, to the extent ownership can exist in them, and you can use them commercially. You stay responsible for how you use them, and copyright in AI-generated work is still unsettled in the UK. This is general information, not legal advice.

What is the best AI image generator for beginners in 2026?

The best AI image generator for a beginner shows the price before each render, lets you choose the aspect ratio, has clear commercial terms and refunds failed renders. On Cat Claw, Seedream is the usual starting point at 3 credits a render, with Seedream 5.0 Pro for reference images and Banana Cat Edit 4K for editing.

How do I keep my AI images looking consistent?

Reuse the same style line, mood and colour palette in every prompt and change only the subject. For a recurring face or product, add reference images: Seedream 5.0 Pro accepts up to 10. On Cat Claw, Kitten Shot turns 1 photo into a reference board, such as a character sheet or a product board, which keeps later images on model.

Is Cat Claw AI suitable for complete beginners?

Yes. Cat Claw AI runs in the browser, shows the credit price before every render and refunds failed renders automatically. Studio Copilot takes a plain-English description and picks a model for you, and in Ask mode it checks before spending credits. Finished images post to around 15 platforms from the same account.
