Trying to load photos from USB memory stick to JD0801-F02 8" digital photo frame and it keeps repeating only a limited number of photos and after numerous searching I still can't seem to get access to built- in memory to get photos transferred so memory stick has to remain plugged in? does anyone know what you should do to save the photos the photo frame and show all images on usb (currently only got 45 as thought it may have a limit)
