I was on Google Images last night and noticed a new feature. You can drag an image from your desktop or w/e (or put in a link) and it will search for that image. What I mean by that is: If I drag a picture of a Blacks Ops Jeep onto the image search bar, it will search Google with the terms "Black Ops Jeep". It knows what the image is. I think it would be useful for having an image of something(such as a screenshot to a game) that you don't know what it is. You drag it to the search bar and it will tell you what the image is. Try it out and see if it works. I tried it with a Cadillac CTS Interior and came out with Cadillac CTS 2008. I also tried with my Blockland Wallpaper and it gave me the result Blockland. Give it a try.

Drag an Image from your Desktop to the Search Bar
Profit?
