Instagram has been immensely popular, especially when considering that it's only available as an iPhone app. And its social features have been at the heart of it, even if Instagram is in essence a photo sharing app.
But it seems that there's no one out there that can ignore or avoid the Facebook behemoth, even MySpace integrated Facebook a while ago, and Instagram is now expanding its own integration with a smart new feature, the ability to upload full size photos the social networks.
All Instagram photos shared to Facebook will be added to a dedicated Instagram folder. There, your friends will be able to browse the photos in full view.
What's more, you can also share Instagram photos from that folder to your timeline or a friend's timeline as well as in private messages and pretty much anywhere on Facebook.
