Community Gallery/Community Events Calendar

Hello again!

I'm wondering if anyone has some insight to a community gallery plugin.

What I mean by that is, I want a gallery plugin that my site users can freely upload to to share images with one another.

I'm trying to implement this on my guild/clan hosting site and this is one of the features they've requested.

Also, I'm looking for a great event's calendar that can be used by clans/guilds to post events and mark specific dates for the entire site to see/respond to.

Thanks again for your great advice and help.
