I am trying to use a 1920x1080 .jpg picture for the Scenea wallpaper, downloaded from Interfacelift.com . All pictures open with no problems on my PC. When I load them on a USB stick and plug the stick in my 40PFL6606H/12 (latest firmware), they show up as present on the USB media but all pictures give a "reading error" when trying to open any pic.

Example can be this one:

Please help on how to solve this problem. I read the help, that the file needs to be less than 1MB, but this example is 561KB - so this should not be the problem.
