Expert Flickr developer David Wilkinson guides you through a series of software projects that show you how to build mashups using the popular photo service Flickr. He explains the process of remixing Flickr on your own web site and then mashing it up. Along the way, you’ll learn how to take advantage of mashup technologies such as REST, Ajax, RSS, and JSON. Plus, hands-on examples will help you gain the skills to design a variety of remixes and mashups that take advantage of Flickr’s core services.
Nicely written, with a good intro to using the Flickr API. Though I found the HTML/CSS/PHP snippets more useful, as learning the Flickr API is easier, for me at least, by playing with it in Python.
