In Windows XP, (I'm not sure about ME at the moment), there is a "My Picture Slideshow" as a screensaver option.
Right click any empty part of your desktop and select Properties.
In the Display Properties dialogue select the Screensaver tab, and then in the Screensaver options click the arrow on the right, scroll down and find "My Picture slideshow" if you have it.
You can set up a slide show fom there.
I have an older IBM thinkpad running ME. A couple of years ago I saw a tip on Tech TV on how to enable the "view as slideshow" function for photo files, just as you can do in XP. I have since had to do a complete reinstall of the OS and can't for the life of me remember how to do this again. It was very simple to do - just a few mouse clicks - but I just can't remember. Any help? Thanks.
