If it was fdisk that changed the format, changing it back may suddenly 
allow the image to reappear.  If it was the format command, FAT partitions 
have a backup FAT table that can be restored.  The DOS unformat command 
uses this trick.  If the files were deleted on a FAT partition, the first 
character of the filenames were masked off and the sector chains freed if 
my memory is correct.  Guessing the first character and hunting down these 
chains can be quite a game.
