MacBook – Desktop Background is blank

I change my background in system preferences and it says my background is a picture, but my desktop is still a blank gray. How can I fix this?

Try opening Terminal, type killall Dock and press return. Dock controls the desktop background in Lion.

If it's still grey after that, try rm ~/Library/Preferences/com.apple.desktop then killall Dock
