Photos are set to advance automatically every 6 seconds. You can suspend photo advancement with the pause/play button located to the right of the "pictures" tab. Arrows located on either side of the gallery allow you to scroll through the album. If you click on the "pictures" tab at the top of the photo, a bar will appear with thumbs of the album and you can select a photo to view. Clicking on the light box will enlarge the photo. Enjoy!
