Image screensavers?

Anyone know of a Webshots-like program that'll automatically watch directories and randomly cycle images as a WinXP wallpaper?  I've been using Screen Paver, but it's a little on the memory-intensive side.  Extra points if it'll do the same for my wallpaper, all as one program, because Pictureshare.net sucks balls since it now has NagScreen 1.0.  :-(

Start->Settings->Control Panel->Display->Desktop->Screensaver->My Pictures Slideshow->Settings->Browse
