Over the next couple of weeks I'll be tidying up the albums in the gallery, removing any that are empty or belong to former members. I notice that some people haven't added anything to their album in a looooong time. You should consider using it more – it provides a more permanent display for your best images than the transient nature of facebook. You don't have to be logged in to see the pictures in the gallery, though you do to add pictures or comments. There is a page of notes on using the gallery under our Educational menu item.
