If you send or receive a lot of photos via email and want a way to track them down, collect them, and share them to Facebook or Twitter, this looks like a handy utility. It crawls through your Gmail, Yahoo, AOL, MobileMe/iCloud, and Google Apps mail looking for photos, then presents them in a simple window so you can do your thing.
Lost Photos is just $3 in the Mac App Store, but also available for Windows.
