This is the first book that shows how to take advantage of both your photos and Flickr's enormous cache, to create new and compelling extensions to the Flickr platform. You'll discover how to take advantage of open source tools (like PHP, Apache, and MySQL) and the Flickr architecture to manage, retrieve, and format photos in imaginative ways. You'll also learn how to build upon Flickr's photo collaboration features to create interfaces for working with others on photo album projects. And you will learn how to take advantage of RSS to distribute photo updates with ease.
