I have a kodak easyshare c813 digital camera. put new batteries in it, also new memory card . turn the camera on and it says internal memory is full. what do i need to do to be able to to fix this problem?

Hi and thanks for coming to FixYa.

To fix this you need to copy the pictures in your camera's internal memory to your pc. That way you won't accidentally lose them.
Then:
Go into the menu of your camera and format your card. Your camera won't save pictures to the card properly if you don't format it first. - You have to format it in the camera, don't use your pc or a card reader.
That will take care of your problem unless.... your card is locked. In that case, unlock it with the switch on the side. Let me know if you have any questions or problems.
