Anyone?
Can't you just set the image to stretch when you make it a wallpaper? Or, just use some image software to stretch it out, though it will look weird as you move it away from it's original size.
If you enlarge an image anymore than say 20% it'll just end up looking like a pixelated mess.
But...if you still wanna give it a go try this site.

If it's low-res it'll look bad either way. Nothing you can do, really.
There's Bone wallpaper here - http://www.scholastic.com/bone/freebies.htm#
Do you mean desktop picture or do you actually mean screen saver?
