After a September reveal, Facebook officially launched its new Photo Sync feature for iOS and Android devices on Friday.
When enabled, Photo Sync will upload any and all pictures taken on a mobile device to a private, locked folder called "Synced from Phone" within Facebook.
Once there, users can decide which pictures to share with the rest of their friends, and which pictures should remain private.
iOS 6 mandatory
Photo Sync appears to work with any version of Android, as Facebook doesn't specify any requirements to use the feature on that particular OS.
Once a user agrees to allow photos to sync from a smartphone, the Facebook app immediately begins uploading the images (up to 2GB) to the website.
How often the device uploads images is entirely up to the user, though new photos taken will by synced as they are taken.
Users can also choose how to sync the photos (via WiFi, cellular network, or both), and can turn off the feature entirely and delete photos from the private folder at their discretion.
For those concerned about data plan overages, Facebook assures smaller versions of the photos (100K) will be uploaded over 3G and 4G networks, while larger versions will be uploaded when connected to a wireless signal.
A prompt to "Get Started" will appear at the top of the Facebook feed in the app when the feature has rolled out to your market.
