Search Google Using An Image
Have you seen an image online and wondered where it came from? Is it a real picture or was it somehow doctored in Photoshop? Using Google's image search your answers are a simple drag and drop away.
Navigate to images.google.com
Drag the image from a folder or your desktop into the search bar that appears in the center of your screen.
The search results look almost identical to your traditional text-based Google search. These results show where the image came from and other related images. At this point I can identify if the picture has a copyright attached and where the picture has been used elsewhere on the web.
