Flickr Web Services
Flickr exposes a variety of services to access their database of public images, in REST (see this article), SOAP (read here) and RPC (here) formats. For more details, go to their API documentation. A detailed explanation of accessing RESTful services is outside the scope of this article, but, in essence is involves generating a url, downloading the result as a string (the Flickr REST service returns an XML file), and then parsing it to get the info we want.
