Yahoo has purchased Flickr, an online photo sharing service, and its parent company Ludicorp. News.com reports that the Ludicorp employees will relocate to Yahoo's offices in Sunnyvale, California. Flickr offers technology that allows users to post photos, sort photos using tags and label different parts of a single photograph. The Flickr purchase comes shortly after Yahoo announced the launch of Yahoo 360, a service that will combine blogging and social networking.
