Flickr is a very popular photo upload and sharing site. Flickr has an excellent tagging, storage, and viewing system, and a lot of bloggers use Flickr for sharing pictures with friends and colleagues. In this chapter, you'll create a page template that pulls in a WordPress user's photos from their Flickr account, and displays these photos in a simple list.
To properly use the techniques in this recipe, you'll need to be working with a theme that you previously acquired or developed. If you haven't started developing a custom theme yet, I recommend using the Thematic theme. It can be freely downloaded from the WordPress.org Theme Repository, at http://wordpress.org/extend/themes/thematic/.
