I have RT(F)M and searched FAQ/support board I think, but I can't find any way (or a coppermine mod) so that (non-admin) users are able to edit the properties specifically of only their own uploaded files in public albums.
It seems to be a simple permissions check missing, as I believe that the information about which user added each file to a public album is in the database (you can see originating user name is captured on the file information on displayimage.php).
Any ideas appreciated, otherwise is it a straight "no" -> feature request?
Coppermine config -> User settings -> Allow users to retain control over their pics in public galleries -> Yes
Doh - simple. Thanks! Next time I will expand all the config options first...
