I have my phone and computers on a more secure network than the TVs and thus have reservations about the trade-off in security of putting all on the same network in order to have Photo Streams/screensaver. My suggestion is that Loading Photos being available, instead of just the phone, from the external USB drive. If this is not possible, could a photo screensaver be added to the Roku Media Player that could be invoked from the Screensaver option? Thanks for considering.
