Profile background images can only be added from your Menewsha Album.

Click where it says 'My Account' near the top of the screen and then on the left hand side under 'Networking' is a link titled 'Pictures and Albums'. From there you'll be able to upload an image from your comp, which you can then use as your background.

The filesize and pixel max are 97.7 KB and 600x600. ;)
