There are several controls to customize your slide show. The slide show will start automatically after 10 images have loaded, be patient. To stop the slide show from automatically advancing to the next photo, uncheck the Autoplay at the top right corner. You can scroll through the thumbnails with the slider bar on the left and click on the photo to view a larger size. You can also use the << or < or >> or > buttons to jump to the beginning or end and to advance one photo at a time manually.
