Re: Password protection of multiple albums
Using "Gallery" as an application you can password protect the album with the built-in permission / group / user system, here you may require the users to be logged in before they can see the albums.
You can use the password module as an alternative to the permission system, e.g. if you just want to send a single password to multiple friends instead of creating some user accounts.
