Tile Finder background image in Snow Leopard I have seen a guide/tip on the internet to make Finder tile it's background by editing ~/Library/Preferences/com.apple.finder.plist however the guide is now outdated and no longer works on Snow Leopard.

Does anyone have any suggestions on how to go about this?
It can't be done right now.  Even if you made a background image in Photoshop the size of your display and used that, you'll find that with certain views (eg narrowed windows), you'll still see the edge of the image.

Someone somewhere just might write an app to do this, and in my opinion it would be popular.

Until then, we're stuck with just colors.
