Instagram images are not displaying on Twitter cards as of Sunday afternoon. Instead, users are being shown an empty white space where a photo should live. A link to the Instagram photo is still included.
Update: A Facebook spokesperson confirmed to AllThingsD that Instagram has disabled all support for Twitter cards. Instead, Instagram shots shared via Twitter will only include a link to the photo's Instagram URL.

Several Twitter users have indicated the problem is only happening on official Twitter applications, while third-party apps remain unaffected.
Several months after Facebook acquired Instagram, the latter company disabled its integration with Twitter cards. The change resulted in users' images being shown in a cropped format, the same treatment received by other images. Soon afterward, Instagram CEO Kevin Systrom explained that decision while promising Instagram would "always be integrated with Twitter."
