The images I have taken have been taken by using Halo 2 PC's built in Screenshot App by pressing F11 and found in my documents/my games/screenshots you can take one every second. The images are saved in TIF format*
I have tons of screenshots uploaded to my facebook account...but you won't be able to see em cuz of my privacy settings...but I've got some to share...
odd, I only attached 2 photos but I get 3 and one is a dupe... :/
