"Unrecognized file format" error message

Took about 20 pics of my daughter on Thanksgiving got home to take the pics off and 8 of them would not show up. I can see them in the camera but they are not being recognized and will not open (in Konqueror). Tried to open with The Gimp and it gave me error messages saying the following: Corrupt JPEG data: 29 extraneous bytes before marker 0xc4

EXIF data will be ignored.:

Where are my pics?

i am trying to take pics from my computer and put them on a SD card. Two of the pics so far have come up with "unrecognized file format" when i try to look at the pics from the SD card, but they are recognized on my computer. one of the pics is one i actually took with my kodak camera and the other one i scanned in. they are all jpegs and i don't understand what i need to do to get all my pics to the SD card successfully.

I've just returned from a trip and while there, I've encountered the error message, unrecognized file format, on the screen from my v550 Kodak camera. I couldn't review the image but the camera continue to take the pictures as normal, I just could not review them.
Getting home I've tried to viewing them but I can't. I don't use the supplied docking station, I just remove the memory card and plop it directly to my PC. The files are there, they are reading as the standard jpeg file, but when I try to open it, I get an message from 'not a valid file'.

Odd set of changing circumstances...truly puzzled by them all. Pictures taken and they showed fine on the camera, downloaded on to the PC and were fine at first, then I got a message saying that the format not understood...checked format all pictures now show as JPC formatnot JPEG... and cannot be read by computer. I checked and the extension on all the picture files is JPC (if I remember correctly....and that stands for Japan Picture ..? Now pictures cannot be opened and may be corrupted beyond opening.
Can this camera not be used in North America with our PCs?


Thought the memory card was at fault...still have the old one... hoping to get the pix off it. Bought a new memory card, took more holiday pictures; seemed fine, and this time we took them to the cruise ship photo lab to have them made into a disc. Pix seemed fine on their computer,vieweed well, but once the disc was made we have half pictures, no pictures, etc.

Took camera to a shop where they installed their memory card into camera and they took a picture....it didn't show up on their memory card AT ALL! Obviously camera not reading to memory card. The odds of two memory cards being faulty is too impossible.

Have had camera for just over a year, used it on two vacations only...both all pictures are ruined. What gives? Is this camera ruined?
