A quick demo of how Google's reverse image search tool can be used to fact-check and research images. Have you ever wondered about the source or history behind an image? Google image search can help provide answers. Whether you're doing research or just curious, reverse image search offers a digital paper trail of where an image has appeared on the internet. All you need to do is drag and drop an image into the images.google.com search bar, paste a URL into the search bar, or right-click on an image when using the Chrome browser.
