Google has announced that they will shutting down panoramic photo sharing site Panoramio, along with its API on November 4th. Originally the company had announced plans for the shut down back in 2014 but due to strong community feedback they postponed those plans until users had viable options.
Sighthound launched Sighthound Cloud Computer Vision API, a computer vision engine service available as a Cloud REST API interface.
Popular iPhone photo-sharing app Instagram is a prime candidate for an API, which is probably why it already has one. Though documentation refers to it as an "unofficial" Instagram API, the fact that it uses the company's own servers makes it seem pretty official. Instagram has not launched the API, nor is an API linked from its home page. Yet, it has a mobile app and right column Twitter integration, both of which likely consume the API.
