Different wallpapers on each workspace in ubuntu

Wallpapers are same on each workspace in ubuntu default,here is a way to make wallpapers different on each workspace,but you must have installed CompizConfig Settings Manager, and you will lose any shortcut on desktop,so install Avast window Navigator for better results.

Now go to System–>Preferences–>CompizConfig Settings Manager(Advanced Desktop Settings)

tick Wallpaper on(if not go to Desktop Cube,click to go to Appearance–>background images),then click to go to configuration page,click New and add the wallpapers you want

Open a terminal window and type code:

gconf-editor

in the next window,go to apps–>nautilus–>preferences and deselect show_desktop on the right of the window, then close it

And Done.
Following is my wallpapers:
