To embed the uploaded image in a lesson, open the lesson and add an image block at the position where you want the image to appear. To do this, click on the plus icon in the block editor or type „/Image“ in an empty block to find and select the image block.
Now you can either upload an image directly to the media library (blue button „Upload“) or select it from the media library (link „Media library“).
Click on an image to select it. It will then be marked with a blue check mark and can be embedded into the lesson by clicking on „Select“.
