We are pretty sure you have a bunch of photos you haven’t seen in a while buried under piles of online newsletters and work and personal emails. Now, you can recover these lost memories with Lost Photos for the Mac. The app scans and shows the photos stored in messages kept on popular IMAP email services, such as Gmail, Yahoo, Hotmail, iCloud, etc. You can download the photos to view, archive, and even share online on your social networks. The app is available for free and exclusively on the Mac App Store.
