Mary,
I'm not sure of other versions of Windows, but XP has a built-in screen saver that will display all the photos in any directory you point it to. You have control of transition effects, timing, etc. I have mine set to display our "Key Largo winter 2003" photos. So everyday I get to see you and Rick, Cody, your Grandson, the Canadian couples on their Mystere, Nest Key, Blackwater Sound, the Boogies, the Apartment #3 geko, Sunsets and New Years Eve fireworks for the dock, etc.
