food for thought. with programs like winrar password encryption is possible, technically the trial version is freeware and could be included w/ your photos, but once it gets into the wrong hands it can be uploaded to megaupload or rapidshare and the password can be found all over the net. so, unfortunately there really isn't a viable way to encryt it. even cs3 and more sophisticated programs that generate hardware codes upon install can be cracked and keygens made.
