When you create a course from a file or a link, we read the words and look for images worth keeping. We pull out the meaningful images, write a short description for each one, and then place the most relevant ones into your lessons as the course is built.
This happens automatically. There's nothing to switch on.
It works for:
• PDFs
• PowerPoint presentations (PPTX)
• Word documents (DOCX)
• web pages you add by link (URL)
To keep your course clean, we leave out images that wouldn't add value. An image is skipped when it is:
• Very small (roughly under 100 by 100 pixels), such as icons, bullets, and tiny logos
• Blank or a single solid colour, such as empty backgrounds or spacer graphics
• A duplicate of an image already pulled from the same source (we keep one copy)
• Very large as a file (over 20 MB)
Every image that passes these checks is saved to your project and made available to your course.
Passing the checks above doesn't guarantee an image lands in a lesson. As each lesson is written, we match the most relevant available image to that lesson's content, based on what the image shows. If none of your source images fit a lesson well, we may use a stock or illustrative image instead, or leave that spot without one.
Every image we keep from your sources is added to your project's image library, so you can place it yourself even if it wasn't used automatically.
To browse them, open the image picker in the lesson editor and choose the From sources filter. This shows the individual images and diagrams we pulled from your files and web pages, whether or not they were used in a lesson.
Two things to keep in mind:
• Images that were skipped during extraction (too small, blank, or duplicates) aren't saved, so they won't appear here.
• Full-page snapshots of your source aren't listed. You'll see the individual images and diagrams found inside the source, not whole pages.
The idea is the same for every source, but how images are found differs slightly:
• PDFs give the richest results. We pull both embedded photos and diagrams or charts that were drawn into the page.
• PowerPoint files are converted to PDF first, so images from your slides come through the same way.
• Word documents contribute the images embedded in the document.
• Web pages are opened and their visible images are collected (JPG, PNG, WEBP, and GIF). For web images, we use the image's existing alt text to understand it.
If you expected an image and don't see it, one of these is usually the reason:
• It was too small, blank, or a duplicate, so it was skipped
• It wasn't a strong match for any lesson's content (look for it under From sources in the image picker and add it yourself)
• It sits behind a login, or only loads after scrolling, on a web page, so it wasn't available to read
• The source was a video or audio file, which don't contribute images
