How to Create AI Images: A Step-by-Step Guide for Beginners

Creating AI images starts with a simple idea: describe what you want to see, choose a suitable AI image generator, and let the tool turn your description into a visual. You can then review the result, adjust your prompt, and generate improved versions until the image fits your needs.

If you're wondering how to create AI images without drawing skills or complicated software, this guide walks you through the entire process. You'll learn how to choose an image-generation model, write effective prompts, generate your first image, and fix common problems. You'll also discover how RunningHub provides different creation options, from direct image generation to customizable workflows, so you can choose an approach that matches your project.

What Do You Need to Create AI Images?

You don't need to be a professional designer to get started. Most beginners can create their first AI image with a few basic resources.

1. An idea: Decide what you want to create, such as a portrait, landscape, illustration, or product visual.
2. An AI image-generation tool: Choose a service that supports your intended task.
3. A prompt: Describe the subject, setting, style, and other visual details you want.
4. Optional reference images: If the selected tool supports image input, you can use an existing picture to guide the result.
5. Time to review and refine: Check the generated image and make targeted changes when necessary.

AI image creation generally involves three approaches:

1. Text-to-image: Generates an image from a written description.
2. Image-to-image: Uses an existing image as a reference for a new visual or a stylistic transformation.
3. Image editing: Modifies an existing image, such as by changing its background or adjusting selected elements.

These approaches are not interchangeable, and individual models may support different functions.

For beginners, a browser-based or cloud-based generator can be a convenient starting point because it may eliminate the need to install software or configure a local AI environment. However, available features and access requirements depend on the service.

Step 1: Choose the Right AI Image-Generation Model

The model you choose influences how the generated image looks and how well it follows your instructions. Some models are designed for general image generation, while others are available through specialized applications or workflows for particular tasks.

Use your intended result to narrow down the options.

For Realistic Images

For portraits, landscapes, and lifestyle photography, look for a model suited to realistic lighting, natural textures, believable proportions, and detailed environments. Describe the photographic style you want, rather than relying on the word “realistic” alone.

For Illustrations and Stylized Art

If you're creating anime-inspired characters, paintings, concept art, or 3D-style illustrations, choose a model that supports your desired visual direction. A clear style description and a defined color palette can help communicate the look you have in mind.

For Product and Marketing Images

Product visuals need a clear composition, appropriate lighting, and a background that supports the product. If you need to preserve packaging, labels, or a particular product shape, check whether the tool supports reference images or relevant editing features.

For Reference-Based Generation or Editing

Confirm that the selected model supports image input and the specific operation you need. Text-to-image generation does not automatically mean that a model can edit an uploaded photograph.

For Beginners

Start with a straightforward interface and a model that matches your goal. You don't need to compare every technical setting before creating your first picture.

For example, RunningHub provides access to different AI creation options, including image-generation tools, AI Apps, and customizable workflows. Its AI image generator offers a direct text-to-image path, while its AI Apps directory lists task-oriented applications.

The key principle is simple: choose a model for the image you want to create, not because it is the most complicated or widely discussed option.

Step 2: Write an Effective AI Image Prompt

A prompt is the written description you give an AI image generator. It communicates what should appear in the image and how the finished result should look.

A useful starting formula is:

Subject + Action or Pose + Setting + Style + Composition + Lighting + Important Details

Here's what each element contributes:

1. Subject: The person, object, animal, or scene you want to create.
2. Action or pose: What the subject is doing or how it is positioned.
3. Setting: The environment or background.
4. Style: The desired visual treatment, such as photorealistic, watercolor, cinematic, or minimalist.
5. Composition: How the subject is framed and positioned in the image.
6. Lighting: The direction, softness, color, and mood of the light.
7. Important details: Specific colors, materials, textures, or other features that matter.

You don't need every element in every prompt. A simple illustration may need only a subject, style, and background. A commercial product image may require more precise instructions about materials, lighting, and composition.

Three Reusable AI Image Prompt Examples

The following English prompts can be adapted for different image-generation tools. Results will vary depending on the selected model.

Example A: Photorealistic Portrait

Prompt

“A young woman sitting beside a large window in a quiet modern studio, relaxed natural pose, soft daylight illuminating her face from the left, neutral beige and gray color palette, medium close-up composition, realistic skin texture, subtle background blur, professional editorial photography, natural expression.”

Why it works: It defines the subject, setting, lighting direction, framing, color palette, and photographic style without overwhelming the model with unrelated details.

Example B: Stylized Illustration

Prompt

“A small orange cat sitting among blue wildflowers in a peaceful spring garden, charming hand-drawn storybook illustration, soft pastel colors, rounded shapes, delicate outlines, simple balanced composition, warm afternoon light, gentle and cheerful mood, uncluttered background.”

Why it works: The subject and setting are specific, while the art style, palette, and mood give the model a consistent visual direction.

Example C: Product Image

Prompt

“A premium amber glass skincare bottle on a light oak table, soft morning sunlight entering from the left, warm neutral color palette, subtle natural shadows, clean minimalist product photography, bottle centered in the frame, realistic glass reflections, uncluttered background, refined commercial art direction. Preserve the bottle's original shape, color, cap, label placement, and proportions as closely as the tool allows.”

Why it works: It specifies materials, lighting, framing, and product characteristics. However, text instructions cannot guarantee exact reproduction of logos, labels, text, or proportions. Inspect the result before commercial use.

One final tip: prioritize the details that matter most. A shorter, coherent prompt can be more useful than a long description containing conflicting instructions.

Step 3: Generate Your First AI Image

Once you have selected a model and written a prompt, you're ready to generate an image.

1. Open an image-generation tool. Choose a direct generator or another interface that supports your intended task.
2. Select a suitable model. Match its supported capabilities to your desired style and output.
3. Enter your prompt. Describe the subject, environment, style, composition, and lighting in clear language.
4. Choose available settings. If supported, adjust the aspect ratio, image size, style options, or reference-image inputs.
5. Generate and review. Check whether the image matches your idea and identify the most noticeable problems.
6. Save or refine. Keep useful results and make targeted changes to improve the next version.

The available controls differ across tools and models, so you don't need to look for settings that your chosen generator doesn't offer.

Your first result is a starting point. Even an effective prompt may produce unexpected details, so reviewing and refining the output is a normal part of the process.

Step 4: Improve Your AI-Generated Image

If the image isn't right, avoid rewriting the entire prompt immediately. Identify the problem and change the relevant instructions first.

For example, compare these two prompts:

Initial prompt: “A coffee bottle on a table.”

Improved prompt: “A premium glass coffee bottle on a light oak table, soft morning sunlight from the left, warm neutral palette, clean lifestyle product photography, uncluttered background, bottle centered with subtle natural shadows.”

The improved version provides a material, a surface, a light direction, a color palette, a photographic style, and a composition. These details help communicate the intended result more clearly.

For important product details or character consistency, consider image-to-image generation or a specialized workflow if the tool supports it. Even then, check each result for unwanted changes. No prompt can guarantee perfect preservation across every model.

Common Mistakes to Avoid When Creating AI Images

Before using an AI-generated image, run through this short checklist.

1. Writing prompts that are too vague: Include enough detail to communicate the intended subject and visual direction.
2. Adding conflicting instructions: Prioritize the most important requirements instead of describing several incompatible styles.
3. Choosing a model without considering the task: Check whether it supports your desired image type and input method.
4. Expecting perfection on the first attempt: Treat generation as an iterative process and refine specific details.
5. Skipping the final quality check: Look for distorted objects, inaccurate text, inconsistent features, and unwanted artifacts.

Generated images may need additional editing before professional publication. For commercial projects, review both the image itself and the applicable usage terms.
