How do I get the slideshow to shuffle all photos on a USB drive, or is there another app I can install to do this? I would have though this would be one of the first things anybody would want to do with photos - just shuffle everything in every folder on this USB stick (like what every electronic photo frame can do). Instead I have to manually select each and every folder and wait for it to go through sequentially. Thanks LG webOS 55" LED TV...55UH617 I think.
