You may have used Yahoo! Photos in a few of other Yahoo! products, including favorites like Yahoo! Mail, Yahoo! Messenger, 360°, Mobile Web, etc. Unfortunately the Yahoo! Photos features in these services will all be going away soon, which means your photos will no longer be accessible from these services. And your photos will definitely not be available from these other services (or anywhere else on the Web for that matter) after all remaining photos are deleted and no longer accessible.
