I've got 7 homescreens on the Hero and the default Android background seemed limiting. So in another thread, someone said to try an app called 'Wallpaper Plus' ($2) from the market. It allows you to set wallpaper without cropping, and set individual image for each Home screen by stitching multiple images together. I tried an older version of it in the android SDK emulator which is running Pandahome with 7 homescreens and it worked. I haven't tried it on my Hero yet since I'm waiting for the 2.1 update before I start buying anything.
