The Python Flickr API kit is a feature-rich Python interface to the Flickr API. It comes with a caching framework and remembers the user's authentication credentials automatically. It supports a variety of communication protocols, and offers different XML parsers to suit different platforms and preferences.
The process of taking your photos and sharing them online with your friends has never been easier. There are several services available to do that today like TwitPic, YFrog and others.

The photo sharing services space seems ripe for the emergence of APIs, which in turn might trigger the next round of innovation from developers.
