Streamzoo, an alternative to Instagram, has just released the Streamzoo API. According to the documentation, the API uses HTTP calls and returns JSON. It joins 341 photo APIs in the ProgrammableWeb directory.
Flickr has announced the release of two new Flickr API methods. The new methods are related to what are known as the Flickr Pandas, an experimental service where several virtual pandas select safe, public Flickr photos they consider interesting, or photos which have been geotagged.
Magickly aims to make image manipulation possible as a simple web service. The Magickly API is very easy to use, and completely open source. It requires no API key, and allows a developer to use a lot of different image manipulations on any web-accessible image. Magickly is an open source, simplified version of the Aviary Effects API, which has a contest ending next week.
