Like many web 2.0 sites, Flickr has encouraged other people to build their own online applications using images found on the site. Through the use of APIs (application programming interfaces), many people have created third party tools and mashups* that use Flickr images. Here are just a sampling of a few …

• Tag Galaxy - visualizes relationships between tags used on Flickr.
• Spell with Flickr - generates image collages of words using Flickr content.
• Mappr - allows you to take Flickr images and paste them on a map
• Flickr Color Pickr - lets you find public photos in Flickr that match a specific color.
• Librarian Trading Card - See examples of librarians who have created their own trading cards.  Create one for yourself @ http://bighugelabs.com/flickr/deck.php.
