You may have noticed this already, but photo-sharing service Instagram has halted all Instagram and stored gallery Cards from Twitter. At first it was reported as a temporary problem, but has been confirmed to be here to stay.
Instagram has officially stopped all photo integration with Twitter, so now your links to photos will work like normal, but there is no way to quickly preview them through Twitter.
Just a few days ago Twitter removed Card support from the social networking site, but today's move is a little more drastic. I guess this is what happens when the bigger social network buys you out, they don't want you flirting with the competitor at all, huh?
