I am finding this new iCloud feature to be more useful than I had anticipated. I don’t take a lot of photos, but when I do, it sure is handy to have them immediately available on all my iDevices (iPad, iPhone, iPod touch) and on my computer too. In my case, the computer is a MacBook, but it also works with a PC.
Note that the computer must be a Mac running the OS X Lion operating system, or a PC running Windows System 7 or Vista SP2. For Windows, you need to download the iCloud Control Panel. For more details on setting up PhotoStream on your PC, see this article.
On a Mac computer, simply go to iCloud in Systems Preferences to enable PhotoStream. For more information on setting up PhotoStream on a Mac computer, read this article.
With Photo Stream, when you take a picture with your iOS device, the photo will automatically transfer to iCloud and will be stored there for up to 30 days. It will also appear on your other iOS devices and your PhotoStream enabled computers.
Once you start adding images to the folder for uploads on the PC, you’ll see them on other iCloud devices a few minutes later. When you take pictures or screenshots with the iPhone or iPad, they’ll also appear on other devices in a few minutes (as long as you’re connected to WiFi).
