Please login to admincenter.
Click on Resources --> Channels . Click the checkbox that says "Publish Reference Files" and then click on the "publish" button for the channel.
After the publish is over, you can delete it.
When I try to delete any image out of the reference files in the admin center, it says it can't delete because a page references this file. However, this page is deleted as well. Is there a place in the admin center to delete pages?
