The pics were taken with a Nikon D5200 on to a 4gig micro sd card. I can see parts of the pics but images are corrupt and the thumb nails up to the large ones seem ok. I would be happy to get the large thumb nails at least since they seem fine. Does anyone know of a program which could recover these as it may just be the header info or some other part which creates the pics. Any info would be appreciated. These pics are from our Holland trip for the remembrance day services at Holton and the Resistance fighter of WWII and Canada's liberation of Holland so these are very important to me. Thanks
