Some features which would improve gallery

I have just managed to get Gallery working and am very impressed with its abilities. A few of features which would be very beneficial though are:

1. The ability to switch on photo owner info in a gallery's preferences. I.e. will tell me who uploaded a picture in an open upload gallery.

2. The ability to specify comments for each picture imported from a zip file, maybe in the progress screen as each is unpacked?

3. When users are not logged in and do not have permissions to view any galleries, a message saying something like: "You do not have permissions to browse the gallery. Please login and try again"

Thanks guys,
