Photobucket Visual Search is a new Silverlight and Windows Live Services application that makes browsing through all those pictures a breezy experience. Photos can be shared instantly through Windows Live Messenger with a single click. Another click allows you to enter the photographer’s library or search for more pictures like the one you’re looking at.
The search tool relies on metadata attached to each image by the person who uploaded it originally. Once users find a photo they like, they can broaden the search by looking at more images that match the characteristics of a given image, or explore the library of the person who uploaded a given image.
