Debbie Durham, I just checked the manual for your camera available here, and this is what it says" Memory card and internal memory full.
■ Transfer pictures to the computer (see page 37).
■ Delete pictures/videos (see page 14), or insert a new card"
You did not tell us if you are using a CF card to add room for more pictures. You can purchase an SD card to store more pictures and videos. You can copy pictures/videos from a card to internal memory or from internal memory to a card. Before you copy, make sure that:
■ A card is inserted in the camera.
■ The camera’s image storage location is set to the location from which you are copying.
1 Press the Review button, then the Menu button.
2 Press to highlight Copy, then press OK.
3 Press to highlight an option.
4 Press OK.
NOTE: Pictures/videos are copied, not moved. To remove pictures/videos from the original location after copying, delete them. Hope this helps, good luck
