I'm not sure why the photo isn't showing on screen as it should ~ but, click on the words "full screen" at the bottom of the black box, and it will take you to the slideshow. Also, you can manually scroll by pressing the stop button, then clicking at your readiness the forward button. I put about 15 photos, with commentary, in this fashion, thinking it would be a tad more enjoyable for the viewer . . . but, might not use this format again. :D Enjoy!
