Hey, there's my post! When I get a desktop, i'd like to do dual monitor setup. I think you can change it under settings, in desktop properties.
Here's mine. I change the BG whenever I take a good picture or according to the seasons.
Also I have a dual monitor setup set at 1920x1200 (yikes!) and 1200x1600. Does anybody no how to get different bg photos for each monitor on a Windoze system? Currently it has the same BG for each monitor. I've yet to find the option to change this.
