[FAQ?] Desktop wallpaper: how big should it be?

[Guest ippoP]

I'd like to put my own desktop wallpaper.

1. How big should it be (480x640?)

2. Which formats are supported?

Thanks.

use "wallpaper set & save" from the market, otherwise the quality of the wallpaper is total crap. needs to be reapplied after every reboot, but it is a free app and works fine.
