I wish to put some recent images onto the desktop 'My Pictures Slideshow' Screensaver. I have all my documents/images etc on a second hard disk F:\ and the slideshow doesn't pick these up. The program files are on drive c:\. Is it possible to get the images in the 'My Pictures' folder showing as a screen saver without copying them all over to wherever the screensaver wants them?
You don't need TweakUI to do this (though you should probably get it anyway).
Under the Screensaver tab of Desktop Properties, select the My Pictures Slideshow from the dropdown and then hit Settings. In here, you'll find a file path location with a browse button. Hit Browse and drill down through the folder tree of the relevant partition, which will be listed under My Computer.
