On the camera or on the computer?

If on the camera, was the card used for something else, perhaps it has other files on it? Or perhaps it was formatted on the computer instead of the camera?

Another explanation might be the card itself is going bad, do you have another card you can use to test?

Did you plug the sd card into your computer, and then edit/rotate images? That can easily end up resaving them in a format the camera can't read. (certainly this is the case on my k-5)

If you take a new shot, can you see that?

If all else fails, reformatting the memory card might fix it...
