I'm looking for a free or shareware program that will let me take my digital camera files and burn them onto a cd in a format that will let me run a slideshow from the cd. The software disk that came with the Canon Digital Elph doesn't have that feature.

a slideshow on what? a dvd player, computer, what?

Oops wasnt specific enough. A slideshow on a computer. Something that will create an executable that will show the pics as a slideshow.

You can save the images and create a powerpoint presentation.
Or just save the images onto a CD and when you insert a CD, I THINK one of the AutoPlay options is view images as slideshow or something close.
Or just open one of the images with Picture viewer and view as slideshow
