Since the disabling of Twitter cards by Instagram, the Instagram pictures service with inside Twitter has been a little strange, and was made by Instagram to attract users to its own web interface.
Now Instagram has taken another step which is a little more drastic to pull users to its service, and has now removed all twitter photo integration from Instagram.
From today onwards Instagram pictures on twitter will only work as links, and Twitter has confirmed that the removal of the photo integration is due to Instagram turning off support and not because of a glitch within Twitter.
The Twitter update on Dec 9, 3:10pm PST confirmed:
“Instagram has disabled photo integration with Twitter. As a result, photos are no longer appearing in Tweets or user photo galleries. While tweeting links to Instagram photos is still possible, you can no longer view the photos on Twitter, as was previously the case. “
