x avatars with a lenth of 60pixels fit into a row that's 1024 pixels long
x = 1024/60
x = 17
y avatars with a hight of 60pixels fit into a column that's 768 pixels high
y = 768/60
y = 12.8
y = 12
y * x = 204 whole avatars in the wallpaper. :O
Anyway, use mine over there. I'm not changing it any time soon.
