After uploading over a dozen pictures into one Photo Album, I tried looking at them in full-screen mode.  A slide show started automatically, and it went too fast.  The first picture only flickered on the viewing area before going onto the next one.  Then the viewing area went black followed by the next picture flickering into view briefly.  Is there any way to change the speed of the slide show?  Can I turn off the slide show to look at individual pictures with the arrows?
