I'm looking for Win7 software, preferably freeware, that can randomly choose desktop background images from a directory (and its subdirectories), stretch the image to fill the screen if necessary, and change the desktop background image every X seconds.
I just upgraded my wife's PC to Win7 from XP. On XP, she was using an old XP Powertoy to change the desktop background images every 3 seconds, and the images were being chosen from a large directory hierarchy of family pictures. This way, our second monitor became a large digital photo frame when it wasn't being used for DVDs, and we often found ourselves and/or our kids watching the pictures.
Win7's own background image settings allow an automatic image change every 10 seconds at least, but the images can only be taken from a single directory and not a directory hierarchy such as our family photos of the past 10 years. Although, if anyone knows some registry hacks to change this, I'm interested.
A good resource is this: http://www.techsuppo...allpaper-changer.htm
Most of the listed programs there either don't support time intervals lower than 1 minute or don't support choosing images randomly from subdirectories or aren't compatible with Win7.
