This post has been updated with comment from Instagram.

Twitter users are no longer able to view full Instagram photos on Twitter, the social network said Wednesday. According to a statement from Twitter, the photo-sharing problems originate on Instagram’s end.

Photos from Instagram are appearing cropped or oddly placed, prompting a flood of complaints from those who use both services.

Twitter acknowledged the problem in a status post, saying that Instagram has changed the way it integrates with the micro-blogging service. Instagram has stopped using Twitter cards, which essentially provide a quick summary of content on the network.

“Users are experiencing issues with viewing Instagram photos on Twitter. Issues include cropped images,” the social network said Wednesday. “This is due to Instagram disabling its Twitter cards integration, and as a result, photos are being displayed using a pre-cards experience. So, when users click on Tweets with an Instagram link, photos appear cropped.”

In a statement, Instagram Chief Executive and co-founder Kevin Systrom confirmed the company has changed the way it integrates with Twitter, citing Instagram’s growing Web presence.

“A handful of months ago, we supported Twitter cards because we had a minimal Web presence. We’ve since launched several improvements to our Web site that allow users to directly engage with Instagram content through likes, comments, hashtags, and now we believe the best experience is for us to link back to where the content lives,” he said.

Systrom said that users will still be able to share photos over Twitter as they did before card integration.

“We will continue to evaluate how to improve the experience with Twitter and Instagram photos,” he said.

Facebook announced it would acquire Instagram in April, prompting user concerns that the service may stop integrating with other networks. In his post announcing the acquisition, Facebook Chief Executive Mark Zuckerberg said that Facebook was aware that Instagram’s integration with “other services beyond Facebook is an important part of the experience” and that it would keep features such as the ability to post to other social networks.

Instagram has been beefing up its own social networking chops as of late, creating Web profiles that let users display their latest photos outside the mobile space. The company launched the pages last month, with big, splashy pages that take clear design cues from Facebook’s Timeline layout.

The service has more than 30 million active users on Apple’s iOS and Google’s Android platforms and sees about 5 million photo uploads per day.
