Apple’s Photo Stream service does a good job of automatically syncing your latest photos across all your Macs and iOS devices—but what happens when you need ubiquitous access to an older photo? Well, you can manually sync your device and transfer it over, or you can just use Photo Stream to your advantage to send it back out to your devices. To do so, just drag and drop any image or collection of images you want from iPhoto or Aperture on your Mac into your Photo Stream, and viola—all of those photos will now appear in your Photo Stream on your iOS devices, for the next 30 days, at which point they’ll “expire” to make room for new memories.
