Updating to version 9.2 isn't possible.
iCloud has finally been released to public. I had high expectations for the photo streaming feature.
For this to work, it said I needed to update iPhoto (9.2) so iCloud could sync photos.
When I click "Check for updates" in iPhoto it doesn't show the update I need. I've checked the Appstore and it already has the iCloud update for iPhoto.
iPhoto was already installed on Snow Leopard. I'm currently running the latest version of Lion (with iCloud) and iPhoto is version 9.1.5.
