Unfortunately, the gallery itself is coded via simple, HTML frames and links, where every picture is manually added in. There is no automation functionality in place, so there's no way to just add in such a feature without an entire rewrite of page. This is why I have the Submissions section to this Forum, where people can upload their own pictures if they wish.
Personally, I despise these php Forum Galleries, as they are far too limiting in the format with which images can be displayed, always having the same, impersonal feel to them that you now see in 95% of the galleries out there. The only advantage they offer, is they make it relatively easy to delete any Spam that's uploaded.
I'd love to have a way to make it all easier, while maintaining the more unique layout of the main page, but I've seen nothing out there that comes close, and I don't have the time to work on actual updates lately, let alone figure out how to write such an application myself.
