Lost Photos (old-photos finder)
Even though this service from software developer Space Inch requires a desktop app for Mac or Windows, Lost Photos is designed to root through your online email accounts to retrieve all the photos you have stored there. Once you've retrieved your photos, you can post them to Facebook or Twitter, email them to someone or just store them on your hard drive. Lost Photos is currently free for Windows users, but you have to wonder if the company has plans to release a paid version of the app for the Windows 8 user interface in the coming months.
Lost Photos | Free for Windows; $3 for Mac
