Simply select the item and capture a portion of the screen. This extension solves these problems by providing a capturing tool in the right-click context menu. Also, the image you are looking for maybe just part of a video stream. In most cases, images are embedded in the background page and hence it is not straightforward to find the actual source of them to be passed to a reverse image search engine.
This is a useful tool to find for instance the actual image name or detect whether this image is unique or is just a copy or a modified copy of an already existed image on the web. 'Reverse Image Search' extension helps you to find similar images or the original image source and its name.
