Can images be added to cloned enviroments?

Summary:

I don't seem to be able to add course images in our cloned environments. Is that correct?

Content (required):

When working in a dev environment, I can upload a cover image to a course and press save and close. However, the image doesn't actually save. I've also noticed that in the course catalog and topic communities, there is now just white space where the course photos go - instead of the blue filmstrip thumbnail. Is that expected behaviour?
