Yes I have a Gallery Password however the hint always appears. If you're signing in as a guest, the hint is not relevant.
Further to trac #591 which was closed as "invalid": Why would I want to give you guest access and have you change the password for every other guest who has to share that one user/password? I'm still not sure about the whole password/login concept.
You wonder why mine's passworded: I've got relatives who don't get along! 'nough said

So, if I want one family to have access to album that includes them not the album that includes the other family, how do I prevent them having access WITH NO PERMISSIONS WHATSOEVER EXCEPT TO LOOK. DO NOT TOUCH ANYTHING. Do I issue them two sets of login/password? One for Albums 1-8 and 10 and another for Album 9?
