HELP! Can my mom make a video tape of my graduation using my Samsung WB210 digital camera tomorrow...?

It sounds like you are storing photos on your cameras memory card. This is a VERY bad idea. You need to transfer all you photos to your computer for storage, and them format your memory card in your camera before tomorrow. Formatting the card in your camera clears off all the data and makes the card ready to be used again. Since you have probably been saving and deleting photos on your memory card, it will have remnants of old photos on it which could cause problems when recording video. You should be transferring your photos and videos to a computer for storage and then formatting your memory card after every dat you use your camera.
