TinEye Reverse Image Search for Firefox is a reverse image search engine. This plugin adds a context menu item that allows you to search for an image to find out where it came from, how it is being used, if modified versions of the image exist, or to find higher resolution versions.It is the first image search engine on the web to use image identification technology rather than keywords, metadata or watermarks. When you submit an image to be searched, TinEye Reverse Image Search for Firefox creates a unique and compact digital signature or 'fingerprint' for it, then compares this fingerprint to every other image in our index to retrieve matches. This add-on does not typically find similar images; it finds exact matches including those that have been cropped, edited or resized. TinEye Reverse Image Search for Firefox adds tens of millions of new images to its database every week.
