Midjourney generates custom illustrations, concept visuals, and lesson headers that look like you hired a designer. For course creators who need visuals that go beyond stock photography — images that actually match the ideas you are teaching — it is the strongest AI image tool available right now. As PR Daily noted in their 2025 AI tools roundup, Midjourney is widely regarded as the best for images among the current generation of AI generators.
What you’ll walk away with:
- High-quality course images with more visual control
- A style reference workflow for consistency
- A prompt template library for every new module
Why Midjourney for course visuals
Stock photography has a sameness problem. Search for "online learning" on any stock site and you get the same laptop-on-desk, person-smiling-at-screen images that appear on thousands of course sales pages. Your students have seen them before. They register as filler, not as meaningful visual content.
Midjourney lets you create images that actually correspond to what you are teaching. If your lesson is about the stages of grief in a counseling course, you can generate an abstract watercolor that captures emotional transition — something no stock library has. If you teach a module on garden ecosystem design, you can create a stylized cross-section illustration showing root systems, soil layers, and beneficial insects. The images become part of the teaching rather than decoration around it.
The tool excels at stylized illustration, concept art, and visual metaphor. It is weaker at photorealism and anything involving text. For course creators, that tradeoff works well — you rarely need photorealistic images, but you constantly need visuals that communicate abstract ideas in concrete ways.
Step by step: Creating course images with Midjourney
Join and get oriented
Midjourney operates through Discord and through their web interface at midjourney.com. The web app has become the primary workspace for most users since its launch in late 2024, though Discord still works. Create an account, choose a subscription plan (Basic at $10/month is enough to start), and spend a few minutes looking at the community gallery to calibrate your expectations for what the tool produces well.
Write descriptive prompts for your course imagery
Good Midjourney prompts are specific about three things: subject, style, and mood. Instead of "an image for my yoga course," write "a serene watercolor illustration of a person in tree pose on a misty hillside, soft earth tones, gentle morning light, minimal background." The more precise your visual language, the closer the output gets to what you actually need.
Think about what each image needs to communicate in the context of your lesson. A header image for a module on "Setting Boundaries" in a coaching course might call for something like "a calm figure standing in an open doorway between two contrasting rooms, one cluttered and one peaceful, soft illustration style, warm neutral palette." You are writing visual metaphors, not just descriptions.
Iterate with variations
Midjourney generates four variations from each prompt. Rarely will the first generation be exactly right. Use the variation buttons (V1 through V4) to create new versions based on the image closest to what you want. You can also use the "vary subtle" and "vary strong" options to control how much changes between iterations. Most course images take two to four rounds of variation before they land.
Use --ar for aspect ratios
Course images need specific proportions. Lesson headers typically work at 16:9 (--ar 16:9). Square thumbnails for module cards use --ar 1:1. Tall images for mobile-first course pages might use --ar 9:16. Add the aspect ratio parameter to the end of your prompt. This is one of the most important parameters for course creators because mismatched aspect ratios mean cropping, which often cuts the most important part of the image.
Download and resize
Midjourney outputs images at high resolution. Upscale your chosen image using the U buttons, then download the full-resolution version. Before uploading to your course platform, resize to match your actual display size at 2x for retina screens. A lesson header displayed at 800px wide should be exported at 1600px. Oversized images slow page loads without improving visual quality — your students on slower connections will notice.
Maintain visual consistency across modules
A course that uses a different visual style for every lesson looks disjointed. Once you find a style that works, save your prompt structure and reuse it. Midjourney's style reference feature (--sref) lets you pass a reference image URL so new generations match the aesthetic of your existing visuals. You can also create a simple style guide for yourself: "all module headers use soft watercolor, earth tones, minimal backgrounds, --ar 16:9." Consistency across twenty lesson images makes your course feel designed, not assembled.
Prompts to try
These starter prompts are designed for common course visual needs. Adjust the subject and color palette to match your topic.
Concept illustration for a lesson header
a gentle watercolor illustration of [your concept], soft natural palette, warm diffused light, minimal background, educational and calming, no text --ar 16:9
Replace [your concept] with a visual metaphor for your lesson's core idea. "Two hands exchanging a glowing seed" for a lesson on mentorship. "A winding path through a forest clearing toward a sunlit meadow" for a lesson on goal-setting. The style keywords "watercolor," "soft," and "minimal" keep the output cohesive across multiple images.
Module thumbnail
a simple icon-style illustration of [subject], flat design, one or two accent colors on white background, clean lines, modern educational style --ar 1:1
Works well for module cards in your course dashboard. The flat design directive keeps the image clean at small sizes where painterly styles become muddy.
Sales page hero image
a warm, inviting scene of [learning context], soft bokeh background, natural light, aspirational but authentic, lifestyle photography style, no text --ar 3:2
For sales pages where you want something more polished than stock but less abstract than an illustration. The "lifestyle photography style" directive pushes Midjourney toward realistic but idealized compositions.
The human layer
Midjourney generates images, but only you know which visual metaphors will resonate with your students. The tool cannot understand that your coaching clients respond to images of open landscapes because freedom is their core aspiration, or that your yoga students prefer soft, grounded imagery over the dynamic action shots that stock sites suggest. That contextual knowledge — who your students are, what they are trying to become, what visual language speaks to their experience — is what turns AI-generated images into meaningful course design.
The prompt is where your teaching expertise shows up. A generic prompt produces a generic image. A prompt informed by your understanding of your students and your subject produces something that belongs in your course and nobody else's. The AI is the brush. You are still the artist.
Course creator tips
Create a visual style document before generating anything
Before you open Midjourney, write down the visual identity for your course in three sentences. What style? (Watercolor, flat illustration, soft photography.) What palette? (Earth tones, cool blues, warm neutrals.) What mood? (Calm and grounding, energetic and bright, professional and clean.) Having this decided in advance prevents the most common problem — generating beautiful images that do not look like they belong together.
Generate all module headers in one session
Midjourney's outputs are influenced by the model version and your recent prompt context. Generating all your module headers in a single sitting produces more visually consistent results than generating them weeks apart. If your course has eight modules, block out an hour to create all eight header images with the same style parameters.
Save your best prompts in a reusable template
Once you have a prompt that produces the right style, save it as a template with a placeholder for the subject. Something like: "a gentle watercolor illustration of [SUBJECT], soft earth tones, warm light, minimal background, no text --ar 16:9 --sref [REFERENCE_URL]." When you add new lessons later, you drop in the subject and get visuals that match your existing course without starting the style exploration over again.
What it gets wrong
Text in images is Midjourney's most visible weakness. Any prompt that requires words rendered in the image — a book title, a sign, a label — will produce garbled or misspelled text. If you need text on your images, generate the visual in Midjourney and add text afterward in Canva or a similar tool.
Hands and fine details remain inconsistent. Midjourney has improved dramatically since its early versions, but close-up images of hands still occasionally produce extra fingers or unnatural positions. For course images where people's hands are visible, check carefully and regenerate if needed.
Cultural sensitivity requires your judgment, not the tool's. Midjourney reflects the biases in its training data. If you are creating images representing diverse populations or culturally specific contexts — a yoga course drawing on South Asian traditions, a cooking course featuring specific regional cuisines — review the outputs critically. The tool may default to stereotypical or westernized representations that do not accurately reflect the culture you are teaching about.
Consistency across prompts takes work. Even with the same style keywords, two different prompts can produce images that feel like they came from different artists. The--sref parameter helps, but it is not a guarantee. Budget time for regeneration and expect that not every image will match on the first attempt.
Frequently asked questions
How much does Midjourney cost for course creators?
Midjourney starts at $10/month for the Basic plan, which gives you around 200 image generations — enough for a full course worth of visuals. The Standard plan at $30/month offers unlimited relaxed generations, which is more practical if you plan to iterate extensively on prompts. There is no free tier as of early 2026, so you will need to commit to at least one month to try it.
Can I use Midjourney images commercially in my paid course?
Yes. Midjourney's terms of service grant commercial usage rights to paid subscribers. If you are on a paid plan, you can use generated images in your course materials, sales pages, and marketing without additional licensing. The one exception is if you are a company with more than $1 million in annual gross revenue, in which case you need the Pro or Mega plan. For independent course creators, any paid plan covers commercial use. On Ruzuku, you upload images directly into lesson steps where they appear alongside your teaching content.
Should I tell students that my course images are AI-generated?
There is no legal requirement in most jurisdictions, but transparency builds trust. If your images are clearly stylized illustrations — watercolor concept maps, abstract visual metaphors — students will generally assume they are designed rather than photographed, and whether a human or AI created them matters less. If you are generating photorealistic images that could be mistaken for real photographs, disclosure is more important. A simple note in your course materials or about page is sufficient.
Add your visuals to a course students can enroll in
Your Midjourney images give your course a distinctive look — something that feels designed, not assembled. The next step is placing them where students experience them: inside the lessons. On Ruzuku, you upload images directly into course steps, where they appear alongside your teaching content, video, and activities. Module headers, concept illustrations, worksheet graphics — they all go into the same lesson flow.
When your visuals and your content live in the same place, students get a polished, cohesive experience without you needing to stitch together multiple tools. Build the course, add your images, and open enrollment.
