When I go to the User Gallery part of the site, and Coppermine lists all of the users who have set up their own galleries, along with a thumbnail, album count, and file count for each user, how can a user change their thumbnail away from being the last uploaded pic? I know that this can be changed for each of the individual albums WITHIN a user gallery, but does the option exist for the actual user gallery thumbnail?
No, it is always the last uploaded pic I'm afraid.
