Instagram Disables Twitter Card Integration

I noticed this the other day while embedding a tweet, from Nick Bilton at NYT Bits "Twitter Loses Ability to Properly Display Instagram Photos":
Welcome to the Photo Wars.

Instagram on Wednesday disabled the ability for Twitter to properly display Instagram photos on its Web site and in its applications. The move escalates tensions between the two companies, which were once friends in the battle against Facebook but have now become direct competitors.

In a status update on Twitter’s Web site, the company said Instagram had disabled its integration with Twitter cards, which are used to display images and content within Twitter messages.

“Users are experiencing issues with viewing Instagram photos on Twitter,” the post said. “This is due to Instagram disabling its Twitter cards integration, and as a result, photos are being displayed using a pre-cards experience.”

Speaking at the LeWeb technology conference, Kevin Systrom, Instagram’s chief executive, confirmed that the company has removed the ability to send pictures to Twitter, and plans to completely cut off embedding pictures on the Twitter Web site.

“We’ve decided that right now, what makes sense, is to direct our users to the Instagram Web site,” Mr. Systrom said, noting that Instagram images will soon no longer be visible on Twitter. “Obviously things change as a company evolves.”

Mr. Systrom did not say when images will cesase to show up on the site.
