Yeah, that was the size required for the contest thing. The idea was to have 4 similar background images that size in a square, to make 4 backgrounds in one. (I'm not a professional either)
Well one of my photos made it into Flickr's Schmap Dallas 6th Edition guide. The photo was from Quakecon 2008, I titled the photo "Double-Wide", but they used it on the blurb about "The Double-Wide" bar. I assume this will just confuse people, but I don't really care :P
Another one-picture update. I've made another multiple-person photoshop cut and paste :P My camera is slowly dying, so it doesn't really like to auto-focus anymore, so I threw a filter on top of this one to try and hide that fact.
