Photos stored in iCloud
From http://www.apple.com/icloud/photos/


  Access all your photos from anywhere.
  iCloud Photo Library automatically keeps all your photos in iCloud, so you can access them on your iPhone, iPad, iPod touch, Mac, Apple TV, or iCloud.com, or download them to your PC. And when you edit a picture using Photos, your changes are uploaded to iCloud and visible everywhere. Just go to iCloud settings, tap Photos, and enable iCloud Photo Library.
