Copy your photo's to disk, put the disk in a protective pouch, seal it and mail it to yourself. When you receive the pouch or envelope that you mailed it in DO NOT OPEN IT. Put it in a lock box at your local bank or a safe if you have one. It's known as a "poor-mans copywrite". Be sure to start a notebook with a list of the photo's that you put on the disk(s). Also, if you have the capability, date and time stamp the photo(s) via your camera as you take pictures.
