Amazon Prime - Unlimited Photos

If you're an Amazon Prime member you now have the extra benefit of free (I love free) unlimited photo storage, making this a good backup alternative with the extra benefit of being able to access your precious's from any Internet-connected device.  Might take awhile to upload your existing stash, as most home Internet upload speeds are pitifully slow, so this is not a project that should wait to the last minute.
