Instagram, the increasingly popular photo-sharing platform for Apple’s iPhone, has always allowed users to export photos taken within the app to other social networks. The service has never allowed users to upload non-Instagram photos onto its platform, however — until now. Hipstamatic, a similar photo app that takes vintage-looking photos, is set to unveil a partnership that will allow Instagram photos to be uploaded to its service, Fast Company reported on Wednesday. “When we launched, it was all about Facebook and Flickr and Twitter, and now we’re seeing a huge shift in our user base toward Instagram,” Hipstamatic co-founder and CEO Lucas Buick said. “We’ve never been a social networking company, but we clearly benefit from social networks. So this will be the first app outside of Instagram that lets you into their network. That’s pretty cool for us.” Hipstamatic is slated to issue an update on Wednesday evening that will bring Instagram integration to iOS devices. The app is available for $1.99 in Apple’s iOS App Store.
