Change desktop wallpaper

Question

Question is just a simple at first view.

I have six virtual desktops. And want to change a desktop wallpaper for all of them at once. There is no such option when I use System Preferences, so I can to select and change a wallpaper only for first desktop. So I repeat this six times.

Is there any way for automation? Thanks.

p.s.: Mac OS X 10.8.2.

Answer 1

Set the wallpaper for Desktop 1, delete all other desktops, then recreate them. New desktops created always share Desktop 1’s wallpaper.
