RevEye Reverse Image Search

Perform a search by image. Choose between the image search engines Google, Bing, Yandex, and TinEye.
This extension allows to perform an inverse image search by right-clicking onto any image in a web site.

You can configure the context menu to contain either a single button with your default search engine, or a cascaded menu with all included search engines.
