use your My Pictures folder (or wherever you store your digital photos on your machine) as the source for your screensaver. Here’s how it works with Windows XP:

• Start Menu/Control Panel/Display
• Find the Screensaver tab, and choose “My Picture Slideshow.”
• By default, this points to your My Pictures folder, but you can point it anywhere you want.

I’ve had this on my ‘puter for years. One unexpected side benefit: my kids are absolutly mesmerized by the hundreds of family pics I’ve got sliding by whenever the screensaver is on (way better than being glued to the TV!)
