You don't have to buy expensive software or be an editing guru to create photo slideshows. Free Slideshow Maker pieces together multiple pictures and you can add audio files to make your slideshow more appealing. It's not as feature-packed as some similar programs, but it works just fine for showing off pictures to friends, and it's easy enough for rookie users.
Free Slideshow Maker supports most picture and audio formats, so there's no need to convert anything. As for outputting the final product, only the AVI extension is supported. While most computers will be able to play these files with no trouble, it would be nice to have a few more options. The main limitation of this program is that you can't choose your own transitions between pictures. However, people who just want to make a simple slideshow may prefer that simplicity, and should appreciate how easy it is to change the slideshow's timing and frame rate. There's even an option to change the frame size to work with larger monitors or HDTVs.
For a simple, no-frills download, the Free Slideshow Maker is fine for producing simple slideshows for showing off photos or making a photo screensaver. However, professional photographers and businesspeople won't be able to do much with Free Slideshow Maker as the output wouldn't be polished enough. They should look for more advanced slideshow-creating software like Picasa and IrfanView.
