We run repeat courses for new student cohorts every few months. Typically, I'll just copy a course and change the start/end/assignment dates. The content copies over no problem, but increasingly, I'm running into a problem where media links (photos/graphics, primarily JPEGs but also sometimes video files) don't work in student view because they're copied from a course the new student cohort doesn't have permission to view. Frustratingly, as a designer, I don't see this issue because I obviously have access to all of our courses, so I have to check every page in student view to see if graphics/videos work or not.
Is there a way to ensure that graphics (file content, both image and video, but also links occasionally) work for students when I copy courses? If I have to manually re-upload media every time I copy a course, it sort of defeats the purpose. Is there a way to make sure it works every time?
