Where was that picture taken? (via Christopher Null : Yahoo! Tech)

Those boxes and boxes (and gigs and gigs) of old photographs make for fun moments of nostalgia, but they can also lead to plenty of confusion, too.

To wit: That interesting-looking house you shot on the family summer vacation 10 years earlier... but is that John Quincy Adams' childhood home or John Tyler's?*

Who knows. But when memory fails, why not turn to the web?

That's the promise of an upcoming technology in development at Google, whose developer says can identify 50,000 unique landmarks worldwide based on a snapshot alone and correctly identify them without the need for humans to get involved.
