With photocast sharing in iPhoto, your friends and family will be able to subscribe to albums you publish on the Internet so they can quickly get your latest and greatest photos. Theyll just need to click the link from the invitation email that iPhoto automatically composes for you, or select Subscribe to Photocast from the File menu. Your album will appear right in their Source list.
You'll just need a .Mac account to share photos with photocasting. If you don't have one already, go to http://www.apple.com/dotmac/ to try it out.
If you need to cancel an album that youve already published, just select the album, and then from the Share menu, select Unpublish.
Photocast sharing will only work if you have a .Mac account, and enough available space on your iDisk.
