Format the card
Make a folder on the card while inserted in your computer called my_pix and put all your pictures in there. Also on a side note put all your mp3s in my_music, ringtones in my_sounds, and videos in my_flix(videos in 3gp format only I think) And all sizes are supported for pictures, I'm not sure about formats.
Your picture is not a supported format to that unit or your picture too big for the new unit.
