Once you click on an album from the top menu, the photo gallery has a slider menu that replicates the top navigation. If this pushes the sub albums to far down just close the left menu and the albums will come to the top. Once you click on a photo to get into the view larger photo you have two ways to navigate. Click the photo on the left or right edge will go back or advance forward in the album. On the top menu bar on the right are arrows to move picture to picture. On the right expandable menu you can see the previous and next thumbnail. The play button in the top menu will activate a slide-show.
