Dunno why I replied so late to this but anyway ... If you try to just set it as wallpaper, it does not work. Since although you get it on your desktop in the middle ... The background color is not the same. Anyway, I'm gonna upload it in 800 x 600 with the right colors, just devised a new way to get that figured out.

 

Made a wallpaper size of the image above, hope anyone out there appreciates it like me. 800x600 dimensions as yet only.
