Revision 5240, 8.8 KB checked in by plg, 10 years ago (diff)

feature 1505: improvement, when there is no photo yet in the gallery, first
shows a connection box (and only this), then if the user is an admin shows the
"Hello %s, your gallery is empty...".

I've also added the ability to deactivate this message. Only an admin can
deactivate it.
