[K12OSN] Default wallpaper for Gnome

[jeff williams]

Greetings...

Although I have worked a lot with KDE, I have little background with Gnome.  
With that being said, I am looking for the instructions on setting the system 
wide default wallpaper for Gnome sessions.

This is a new K12LTSP installation, and I am pretty low on the configuration 
learning curve.  BTW, there is no discussion of this which I can find on the 
K12LTSP WiKi.

Many thanks.
