Hi there, I have a folder full of desktop pictures and I like to have OS X change the picture at random every 15 minutes. I recently upgraded to dual monitors D), and I'm wondering if it is possible to have the backgrounds in sync at all. Like, can I have a background span the two monitors? I don't think I can. Or, is it possible to at least have them display the same picture? Right now I might have an ocean on one screen and a picture of new york city on the other... I'd like it if they could be the same. Like both of them having the same picture, and then in 15 minutes, changing again.
