The new Shared Photo Streams feature in iOS 6 is a great way of quickly and easily sharing photos directly with friends and family directly into the Photos app or into iPhoto or Aperture on OS X. For those who don’t own a Mac or iOS device, however, Apple also allows you to publish your Shared Photo Stream as a public web album directly from your device.
When creating a Shared Photo Stream, simply toggle on the Public Website option—you can even leave the “To” field blank if you only want to share your Photo Stream on the web. Once the Shared Photo Stream has been given a name and saved, simply tap on the blue arrow beside the Shared Photo Stream name to return to the sharing screen where you will see the URL displayed along with a Share Link button to easily allow you to send the link out to friends and family via e-mail, Messages, Facebook or Twitter. The web version of the Shared Photo Stream uses a fixed Apple template that cannot be customized, with photos presented in a tiled view in order by date added to the Shared Photo Stream with the most recent at the top.
You can also toggle the Public Website option on for any of your existing Shared Photo Streams or turn it off at any time if you want to make your Shared Photo Stream private again.
