I post at a bunch of different forums but I love the Phandroid forums the most Here is a site I use for wallpapers. They are a little "out there", but they are very artistic. All of the images come in different sizes. Check it out. HD Wallpapers | Dizorb | HD Wallpapers and Design Resources EDIT: If I were you (and this is what I do), I would pick the 1024x1024 iPad resolution so you can crop it perfectly and it will be nice and crisp.
