How to Create AI Images for eLearning: Prompts, Styles, and Consistency

If you’re using AI to generate learning visuals, the difference between “usable” and “generic” comes down to one thing:

How you prompt.

This guide gives you a practical, repeatable approach to creating AI images that are:

• Relevant to your learners
• Consistent across your course
• Aligned with your brand

What Is the Best Prompt Structure for AI Images?

Use this simple framework:

AI Image Prompt Formula

• Style – photo, illustration, icon
• Subject – person or object
• Action – what is happening
• Setting – where it takes place
• Details – attributes, mood, objects

Example

“Digital illustration of a customer support agent assisting a client via headset in a modern office, calm expression, dual monitors, natural lighting”

Why Your AI Images Look Generic (and How to Fix It)

Problem:

You’re too vague.

Example:

“Person using a computer”

‍Result:

Generic, often unrealistic image

Fix:

Add specificity

Example:

“Healthcare administrator in a hospital office reviewing patient data on a desktop computer, mid-40s, professional attire, realistic environment”

How to Create Consistent AI Characters

For scenario-based learning, consistency is critical.

Step-by-step:

1. Generate a base character
2. Save that image
3. Use it as a reference
4. Change one element at a time:
   
   1. Expression
   2. Pose
   3. Setting

Tip:

If results drift, restart with the original reference image.

How to Keep Visual Style Consistent

Use consistent style phrases:

• “Editorial photo” (realistic)
• “Digital illustration” (balanced)
• “Modern corporate illustration” (training-friendly)
• “Whiteboard line drawing” (simple concepts)

Add brand alignment:

• Include color descriptions
• Use hex codes if supported

How to Create AI Icon Sets

You can generate multiple icons in a single prompt.

Example approach:

• Define style: “modern line icon set”
• Define colors
• Specify layout (e.g., grid)
• List concepts

Example output:

• Laptop
• Document
• Workflow
• Lightbulb
• Checkmark

These can then be split and reused across your course.

How to Improve Representation in AI Images

AI defaults to biased or generic outputs unless guided.

Always specify:

• Gender
• Ethnicity
• Age
• Setting

Example:

“Retail employee in a small urban store in Southeast Asia assisting a customer, realistic environment”

How to Improve Existing Courses with AI Visuals

You don’t need to start from scratch.

Workflow:

1. Identify weak visuals
2. Generate improved replacements
3. Maintain consistent style
4. Replace incrementally

Example:

• Before: Original course visuals
• ‍After: AI-enhanced version

How to Scale AI Visuals Across Learning Content

Creating images is one step. Managing them is another.

With dominKnow | ONE, you can:

• Reuse visuals across multiple courses
• Keep styles consistent across teams
• Update visuals globally
• Manage multiple languages in one course

This turns your prompts into a repeatable system—not just a one-time task.

Quick Checklist: AI Images for eLearning

Before you finalize an image, ask:

• Does it match the learner audience?
• Is the style consistent with the course?
• Does it support the learning objective?
• Can it be reused elsewhere?

Final Tip: Practice and Iterate

AI image generation is a skill.

Even experienced designers:

• Generate unusable images
• Refine prompts multiple times
• Experiment with styles

The difference is having a process.
