I play via steam, and can't find them for the love of god.

Just a little nooby question:
Anyone know where the hell the pictures you take in-game are?

okay, thanks.

I know that, a bit, but is there a mod?

While waiting for a game, I notice that one of "backscreen" thingy notes that there are more "possible scenarios". The one i am most interested in is the "chemical warfare" one. Is there a mod or something that lets me play some chemical warfare? Because i need a break ...
