There are small photos below the large photo that you can click on to see that photo. You can also click on the small ( - ) and ( + ) symbols to move to the next photo. There is also a play ( > ) and pause ( II ) button to stop and start the scrolling. You can also go to full screen by clicking the last button on the right.
Below are the same photos but only in a different viewer. I have been informed that you can’t right click on the photos above and save them to your computer. The viewer below will allow you to right click on the photo and bring up the (Save Image As) option. The controls on this viewer are a little different, the arrows on left & right side advance to the next 10 photos. (The 10 photos are show on the left.) The + & - move to the next or last photo and the center arrow is the play button.
