Not all members would necessarily want their pictures up publically on the board in a gallery.
Anonimity is a very useful feature of forum membership and I can think of several people who wouldn't want their pictures for the world to see.
Also you must remember that even though you have to be registered to post on the forum,
anyone can view it and there are some very strange people out there.
It isn't always a good idea to let too many personal details out online, you never know who is reading them.
