thanks!! that would be the one : ) allthough it seems have been in a larger resolution in the picture I linked. I don't think the guy has stretched it much cause I don't spot that many pixles and there's no copyrighttext on that one either. anyway thanks a bunch man!
It's the same image; as far as I'm aware no bigger version has ever been made available. The reason there's no copyright on the wallpaper is because it cuts off where the copyright would be shown, or is simply hidden by the task bar.
If you compare the two you can see that the wallpaper version has actually been stretched vertically.
