Don’t fall asleep on Yahoo!’s shoutout to save your photos before Y! photos disappears. They encourage you to migrate the photos to one of a number of popular photo-sharing sites, not just Yahoo-owned Flickr, however — by signing in to photos.yahoo.com and agreeing to migrate my Y! Photos account to Flickr, I received a 3 month extension to Flickr Pro.
(OK, so I guess I did have one photo in there — from maybe 10 years ago in Costa Rica).
