I'm not in love with the app or the picture management on the website but Flickr currently offers 1TB of photo storage at no cost..

My biggest annoyance with Flickr is that it doesn't treat RAW files as photos.. I wonder if Amazon will?

Time to use steganography(http://en.wikipedia.org/wiki/Steganography) to store data in the photos :)?
