I was given a Philips Photo Frame Model 7FF1 and have used it to display photos from my camera's SD memory card and some I downloaded to the unit's memory from my laptop via the provided USB cable and software. What I want to do now is download a larger file than the unit's memory will hold (about 50 pix), but I don't know how to download to an SD card or another device that might work, e.g., a USB drive with the Type B connector. Can someone tell me how to download to an SD memory card without having to buy a load of additional accessories?
