Have you ever found a pic you wonder where it come from?
Like say--a coat in a random pic from the net?
Put this pic (pic or URL) and this search engine will find it for you. Good for research or finding that dress so and so is wearing on the red carpet and wonder where it came from.
I saw a coat mentioned with a pic somewhere--found it in seconds on Tin EYE! (oh Etsy you have such cool things!!!) I just happen to find this site reading an article on a psychology site.
