Flickr is an online photo management and sharing application.

Flickr enables its user to show off their favorite photos and videos to the world, securely and privately show content to their friends and family, or blog the photos and videos they take with a cameraphone.

Flickr helps people make their photos available to other people who matter to them and enables new ways of editing, organizing, and sharing photos and video.
