How do I hide media in the Site Library or in a Collection?
Instructors and site Organizers can hide video, audio and images located in either the Site Library or in a Collection. Media cannot be hidden in a user's My Media Space.
Click Site Library (or a Collection)
At the bottom of the thumbnail for the item, click Details
This displays the details page for that media item.
Uncheck Public, then click Save
Students and site participants will not be able to access the hidden (private) media. Instructor and site Organizers will still be able to access the media.
Note: Hiding content in the Site Library does not hide the same content in a Collection. Hiding content in a Collection does not hide the same content in the Site Library.
