As teacher create some module in the course, tick "Show description" and add images to the description Set the access restriction for this module so the students do not satisfy it (for example, set the date in the future) Create a label with images and access restriction Use another browser as a student, go to the course page and make sure you can see images (but there is no link to the module). Open image URL in a separate window and hit refresh to double check, leave them open As a teacher edit both modules and change "access restriction" closing the eye (which means hidden unless available) As a student you should no longer be able to see description of the first module and the label on the course page. Make sure the images in separate windows do not display. As a teacher "open the eye" for access restriction for the first module but untick "Show description" Again, student should not be able to view the image embedded in the description by accessing the URL directly
