Images are stored on the memory card as a stream of binary values (zeros and ones). Basically the only thing that can happen to alter the image that has been stored is either one or more of these bits become corrupted during or after the writing process or one or more of the memory storage locations become faulty. Usually either of these conditions will result in an error while trying to view or retrieve the image or images whose information is stored in the corrupt or faulty memory locations.

The bottom line is that either your images are exactly as they were stored or there is some missing or corrupt information affecting specific area(s) of the image. It is possible although unlikely that the corruption could be in the area of the image file that contains header information such as EXIF data, colour pallatte information, etc (depending on file format such as TIFF, JPEG, etc) in which case the image could appear radically different with all sorts of strange artifacts and/or colour corruption.

Hope this helps. :lol:
