The Windows Live Spaces control is a client-side browser JavaScript object that enables visitors to use their Windows Live Spaces photos with your Web site.
Instead of uploading the same photo to multiple sites for different value-added services, for example, the user could simply select one of his or her Windows Live Spaces photos from the Spaces control. The user saves time and effort in completing the order, and you gain the benefits of a photo store for your Web site without having to implement, maintain, and provision data storage and management UI on your servers. The user maintains control of his or her photos, while you focus on providing services with the photo the user gives you.
