Photocasting

Another way to share photos while on the go is Photocasting. Photocasting publishes iPhoto albums to your .Mac iDisk so other iPhoto 6 (or later) users can subscribe to them.

A subscriber views a Photocast in iPhoto, just as they would any other album of their own. In iPhoto preferences, a subscriber can determine how often iPhoto checks the Photocast for new imageshourly, daily, weekly, or manually.

When you subscribe to a Photocast, copies of the photos are downloaded to your computer to be used however you wantfor web pages, print projects, or just viewing.

To publish a Photocast, you must have a .Mac membership, be running Mac OS x version 10.4.4 or later, and using iPhoto 6. Subscribers must be running Mac OS x version 10.4.4, but they don't need a .Mac membership or iPhoto 6 (they can view the Photocast in Safari).

To Photocast an album:

1.	Open iPhoto. From the Source list, choose an album to publish.
2.	Click the "Photocast" icon in the iPhoto toolbar (below-right). Or from the Share menu in the menu bar, choose "Photocast."
3.	In the sheet that drops down, choose a photo size from the pop-up menu.
4.	If you want changes to the Photocast album to automatically update on your iDisk, choose "Automatically update when album changes."
5.	To add password protection, check "Require name and password," then type a name and password in the text fields.
6.	Click "Publish." The photos are uploaded to your iDisk. When the upload is complete, an alert window tells you the address (url) of your published album (below).
7.	Click "Announce Photocast" (above) to create an email that contains the Photocast address and instructions to click the address to subscribe to the Photocast. Subscribers who don't have iPhoto 6 can copy and paste the Photocast address into Safari. If you set a password, use this email to tell the subscribers what the name and password is.
8.	Click ok.

When a potential subscriber receives your email announcing the Photocast and clicks the link in the email, iPhoto opens (if the subscriber has iPhoto 6) and downloads the photos. A sheet drops down from the iPhoto title bar asking if they're sure they want to subscribe (shown on the right). If you set a password for the Photocast, a visitor will be asked to enter it in the fields provided.

When you make changes to the Photocast album on your Mac, the change is automatically uploaded to your iDisk. Subscribers can click the Refresh icon next to the Photocast album in the Source list to check for updates.
