There are a few ways to create a Photo Stream. You can do it from a list of pictures in Albums by clicking Edit at the top right and selecting the photos you want to share. Tap the Share button at the lower left and select Photo Stream. Photo Streams can also be created by tapping the Photo Stream button at the bottom of the Photos app and hitting the Plus button. Both methods lead to the next screen, which allows you to choose recipients, name the Stream, and decide whether to make this stream publicly available on iCloud.com.

Tapping "Next" brings you to the final screen, where you can add comments. When done, simply tap Post. Recipients will get push notifications on their iPhone, iPad or iPod touch and a swipe to unlock brings them to your stream. (Non-iOS users can see the images on a specially created Web page.) If you want to add more photos to the stream, tap the middle of the bottom row of icons in the Phone app and add them.

Shared Photos uses iCloud, which, unlike MMS messaging, is a free service.

Shared Photo Streams is a quick and easy way to share photos with specified people.

My biggest gripe with Photo Streams? That recipients can't add their own pictures to your stream. They can comment, they can Like, but they can't add photos. The only option is for them to start their own Streams, which is a shame since Photo Streams would be a great way to share vacation photos into a single location. Hopefully, photo-adding from subscribers will be available down the road. Still, I find this feature useful; it'll be a huge hit in my family.
