To keep the photos in a visible resolution most are 20k to 40k in memory size.  A 14,400 modem will take 24 sec. to load a 40k picture.  A 28,800 modem will take 12 sec. to load the picture.  If the Internet is busy or your computer is less than 200 MHz these times could be doubled. If the program does not allow you enough time to view the photo, exit the auto slide show and view the photos manually by clicking on the thumbnail photo.
