Moving Images to Other Categories
Image Tools - Edit Image
As admin, I cannot (edit) move images from one category to another category unless that other category is set up to "Allow Other Users to Upload to Category."
Somehow an access override is needed for admins to move an image to "any" user's category.
Hopefully I didn't miss another way to make these moves. Maybe something needs to be added to "Admin Options" and incidently, I like "Set Category Image" being an admin only function.
