In picture 1, I'm the one in the white rolled-up shirt preparing to issue a beatdown to the medusa. To the left as you're looking at the picture(my right as I was sitting there) is Redhawk, one of the three people I came up with.
In picture 6, the female gamer would be IndianaJ, one of the others of my group of friends.
I can't say enough about how amazing the 3-d map from the Call of Cthulu game was. Frito KAL, the third of my group of friends, played in it in the morning, and I kept coming over to gawk at it.
Picture 30 is Frito KAL (third from the right, female with glasses) and myself (next to her), in the Vampire: the Masquerade game from the afternoon. The original group was slated to be me, Frito, IndianaJ, and one other guy with our female GM. Frito and I commented numerous times about the completely atypical nature of our group for a Vampire game: 3 females, and only one person wearing black.

If I look extrememly confused, it'd be because I'd never played Vampire before. But I received a typecast Toreador, and since I'm a bit of an artsy performance sort, it wasn't too hard.
I'm just sad that nobody got a picture of the pickup Exalted game late night wherein Frito and I decided we needed to demonstrate the Fastball Special-ish maneuver that our characters were dropping on a bunch of unsuspecting enemies.
