Allow registered users to rotate images?

[Amorget]

I have a couple public albums that I would like other registered users to be able to crop/rotate images in that album.  I set it up for a family vacation and I'd like the rest of the family to be able to help with getting all the images rotated to the proper orientation.  I've set the album to allow Visitors to Upload Files, but I can't find any setting to allow the Rotating.

Thanks,
Douglas

Registered users can only edit their own files (which they uploaded with their account). I see the following options:
1.) Add all users to the 'Administrators' group (not recommended!)
2.) Create a new regular user and assign all images to that user (you can do that with a simple SQL command). Now give the login data (user name/password) to your family members. Drawback: you'll lose the data which user originally uploaded the image.
3.) Modify Coppermine so regular users can rotate images of other users.
