We utilize a very large gallery and at times there is a need for some mass cleanup. We have noticed the following items could be improved:
Currently there is no option to select multiple images to change owner, must be done one by one. You can hide/delete/etc, but not alter ownership.
Currently there is no option to move images into another users album if moderator/admin. You can only move them into albums you have created.
If an album has ownership changed, there is no option to apply that change to the images inside the album. Therefore the album is under a new owner, but the images remain under the original album owner. This is ok in some cases, but undesirable in others, an option would be helpful here.
