How do I view my iCloud Photo Stream online?

Solution 1:

Update: Apple now allows you to share your Photo Stream with others. More info on the official Photo Stream page here

At the moment no. The only way to access your stream is from a Lion Machine using either iPhoto or Aperture, or from another iOS 5.0 device with Photo Stream enabled.

I am not entirely sure if Apple is going to allow a sharing portal, however at the moment I take the images I want to share and upload them to Flickr through iPhoto once they are in my Photo Stream.

I suspect they currently use Photo Stream as a personal backup and sharing solution between devices, and not global sharing.

Solution 2:

There is also already a mechanism to sync PhotoStream photos to Windows PCs.

See the PC instructions on 'How to set up iCloud'.

I've used this and it works well. It adds a new folder to your PC, wherever your pictures are currently stored (e.g. the Pictures library, if on Windows 7).

Once they've been synced to the PC, you can just upload them using whatever software you'd normally use...
