No you cannot transfer to the USB stick without a computer.The photo frame plays jpegs only for photos and you can plug in a SDHC card up to 16gb and play your photos from it. If your camera takes jpegs then you can use the SDHC card in the frame. Plus you should keep a backup of your photos incase of failure of USB stick or SDHC which would require reformatting to fix and that would erase all your photos, music and video files
I have not tried this, but I think you will have to use your computer to do this. There is very little file handling capability built in to the NIX frame software. I had a seperate SDHC card which I added all my photos to.
I have not tried this, but I am pretty sue you cannot fo what you suggest. I think you will have to use your computer. The software on the NIX frame is not sophisticated enough to do all the file handling you are looking for.
