PDF Slideshow enables you to create PDF files with your photos and pictures as Slideshow. If you open the file in Acrobat Reader you don't get a static view to your photos but you will see your photos as slideshow.
It is the same thing Adobe Photoshop Album makes with your photos. You don't need any special player any more. You can give away the Slideshows and everyone with a newer version of Acrobat Reader can view it!
