Fast Image Research von USA Cyborg

Heavy reverse image search user? This free extension adds a simple "Research Image" option to the right-click context menu of Web images. Researching an image will automatically retrieve reverse image search results from your choice of Google Images, TinEye, Yandex, Bing, or a combination of these. Results are loaded into new tabs. You can use the data to find out who is using your own images, or help narrow down the subject matter of an image you found.

Note that in order for Google Images to work correctly you need to enable JavaScript. You may need to clear cache after enabling JavaScript.
