Attached is a little shell script which will cycle the next image from a
list onto Gnome's desktop background.
It's fun to use in from a cron job, or, say, from .bash_profile [if
DISPLAY is set] to change the desktop background every time you pop a
term...
Randomizing a list of images is left as an exercise for the student :)
[I note that you asked about Gnome 2.6; I'm running 2.4 on this system,
but I imagine it still works the same way]
