One of the main features of iOS 6 is Shared Photo Streams, and alongside today's iOS 6 release and Mountain Lion 10.8.2 release, Apple has also released updates for its digital photo suites, iPhoto and Aperture. Both iPhoto 9.4 and Aperture 3.4 include support for Shared Photo Streams on OS X Mountain Lion. With Shared Photo Streams, iOS users can share images directly from their devices with other iOS 6 users without having to email, SMS, or iMessage them to a bunch of people. It's really Apple's own photography social network. Check the Mac App Store or Software Update to get the latest versions of iPhoto and Aperture.
