I like the options that gizmo's mentioned
The Flag a forum as a Gallery is a great idea,
the reason i say this is my own personal view and its this.

I remember being pointed to another piece of software,
and i was horrified to how bad it looked, and to be honest
it turned me away from the product because there was no
on off option.

Images sizes is one of the important things i would like
to mention, being able to control the sizes by height or width.

Flagging it as there personal gallery wink
I like the idea of that smile
(Easier to spot a perv lol)

Good, luck with the development, and cant wait to see it
in action.
