I want to have my wallpapers automatically change from a designed set. However, I am currently stuck with a blue screen that I cant get rid of.

I have yet to find any programs that work. Desktop Nova only works for gnome 2 and when I tried WP-show, it just stopped me from using any of my pictures at all and actually set the blue screen up.

I have also tried xscreensaver and Wallch, but even with wallch running, all i get is the same blue background.

My OS is Mint 12(Lisa) at 64 gigs.
Its Gnome 3

Any help?
