Click on the green arrow  (>) to start the SlideShow.  If you would like to stop the slideshow to look at a picture just click on the = symbol.  To start it back the = symbol turned into an > , just click on the arrow.  The Slide Show is 12 minutes long.  You can stop it at anytime.  The music I had to choose from did not fit our SlideShow.  Ihope you enjoy it.  Melva
