If you’re concerned about image theft, then this post is for you. Using Google to do a reverse image search is one of the easiest ways to find unauthorized copies of your photos online. The service has been around for a while, and is traditionally meant for people looking to find specific images online. By using this info, you can also find your own images all over the web.
Conducting a reverse image search using Google Images takes your image as the query (i.e. search term), and locates images with visually similar elements (colors, textures, patterns, etc.) as well as similar text descriptions (metadata and captions).
