Everyone knows how to use Google Image Search that lets you quickly find images on the Internet. But not everyone knows about the search by image, that can help you in a wide variety of cases. Sometimes you want to search for the sources of images, or maybe you have an image on your computer or found one online, and you want a high-resolution version or want to check if someone has posted it online. Or perhaps you want to check the authenticity of the latest WhatsApp forward you received. Or you have a picture of a table, and you’d like to buy the same one, or you’ve seen a picture of a cartoon character you are not able to recognize. These are all scenarios where Google’s Search by Image tool can be handy.
