A thing I’ve been missing in Instagram — ever since I noticed that Path did it right — is that Instagram photos shared on Facebook were only an entry/story on your wall/timeline; The actual photo remained on Instagram and wasn’t actually uploaded to Facebook (*).
Starting today, when you choose to share Instagram photos to Facebook, your images will automatically be added to an “Instagram Photos” Facebook album visible to your Facebook friends!
The photos will appear full-sized in the News Feed along with the caption that you’ve added to the Instagram photo, and a link to the image’s public URL. This change will also display your Instagram photos beautifully in your timeline.
