So far this is the best I could get it to look. This is a couple different pictures cropped, resized, blurred, etc. etc. I had to go with a straight black background instead of the other one I had because you could see the edges of the cropped pictures really bad no matter how much I blurred/pixelated it.
*edit* Took down other thumbnail. Finally came up with one that I like better, and am actually quite happy with.
