Instagram announced the change — naturally — on Twitter:
They said it would never happen… Twitter Card previews start rolling out TODAY.
Now, when you share an Instagram link on Twitter a preview of that post will appear.
In December 2012, Instagram removed Twitter previews to direct more traffic to its website. Today’s change adds a summary card, which shows a small version of the image and still requires that users click through to see any detail. It took Instagram nearly a decade to slightly compromise and make sharing on Twitter suck a little less.
