Pretty useless because...

…it only finds photos that you sent and only within the last 24 month. That might be a restriction of Yahoo and Google (where I searched in hope of finding photos from 2004 and 2005). I found only photos I had sent to people up until 2012. I’ve had my Yahoo account since 1998 and it didn’t produce anything older than 2012. I even changed the settings in the app and set the calendar back to 1998 but it stopped searching prior to June 2012.
