You’ve got a photograph of whatever, say a little old church or beautiful scenic, but you have no idea where in the world it’s located. You want to know. The picture doesn’t say, and Google Image Search crapped out. What next?
Try the Where Is This website. It’s a search resource to bookmark, not an automated solution. Submit the picture; if accepted, the site’s admin will post it, and if any of its users recognize it, they’ll pin it on Google Maps for you.
They don’t always succeed, but according to their stats, so far they’ve had over 8K successes. Worth a shot!
