Some people I know have been complaining that they are not able to see the option for the new PhotoStream feature in iPhoto 11. Once you turn on and setup PhotoStream on your iPhone, iPad, Apple TV or Mac, you will magically see any picture you take on one device show up on the other devices! It’s pretty neat once you get it working properly.
To figure it all out, first head over to System Preferences and click on iCloud.
Now you will see a list of programs that work with iCloud to back up and sync your files, contacts, mail, calendars, photos, etc. You should see an option for PhotoStream. Make sure that is checked. If it’s greyed out or disabled for some reason, keep reading.
Now if the option for PhotoStream is greyed out in iCloud, then you have to check a few other things. First off, make sure you launch the AppStore program and download the latest updates to iPhoto 11. By default, iPhoto 11 does not support PhotoStream. And downloading the latest version of OS X Lion will not update iPhoto. You have to manually go to the AppStore and click on Updates and then install the latest version of iPhoto.
Now if you already downloaded the latest version of iPhoto, you need to make sure that PhotoStream is enabled. You can do this by going to Preferences under the iPhoto menu and clicking on PhotoStream.
Make sure that Enable Photo Stream is checked and that you also have Automatic Import and Automatic Upload checked. Now to add a photo from iPhoto to your PhotoStream, just select the photo and then go up to the Share menu and click on PhotoStream.
Once you have done that, make sure to go back to the iCloud option in System Preferences and check the box for PhotoStream. After that you should be good to go.
That’s pretty much it! You need to make sure you downloaded all the updates to Lion, all updates from the Mac AppStore, then enable PhotoStream in iPhoto and then make sure to go to iCloud in System Preferences and check it off there so that it uploads the photos.
