Setting up Dual wallpaper on dual monitors

if you are using dual monitors and you would like to set up dual wallpapers on both the monitors. Then it’s not directly possible. I know that there is something called NView from NVIDIA. But i didn’t liked it too much. It’s my personal view.
After googling a bit i found nice tool called “wallmaster” which is free and source is also available at codeplex :
