From Space Inch:
Lost Photos discovers all the photos you've ever sent or received stored in your email account (see list below to make sure it works with your email account). Explore and easily share them to Facebook, Twitter, iPhoto, and email. We bet you've got a ton of amazing stuff in there!
In the past, you would lose old photos in attics and closets-- now we're losing them in a modern equivalent, our email. If you think about it, the photos that you've emailed to friends and family are often the ones you care the most out. You probably have years of emailed photos - to you or from you - lost deep in your email inbox and archives. Have hope! Lost Photos will find them.
Just imagine the pictures you haven't seen in years-- photos with friends and family that you don't even remember existed, from places you've lived, places you've visited, and moments you've captured. With Lost Photos, you'll find them again and be able to quickly share them in a more permanent place.
Lost Photos will find your lost treasure!
All photos are downloaded to your hard drive and easy to transfer to a storage device and view in your favorite photo viewing program.
