TinEye is a reverse image search engine that accepts images that are uploaded from the local computer but also images located on websites. The second method requires some explanation. It is possible to point the search engine to an url of an image or to point it to a website. Pointing it to a website will retrieve all images located on that website giving the user the choice to select any of them for the reverse image search.

The quality of the results depends a lot on the selected image. TinEye will display the number of related images that it found in its database which is currently containing 1.04 billion entries. A quick test for images on Ghacks brought up mixed results. A search for the Firefox logo used on this site returned more than 2000 results while a search for the Ghacks logo returned a handful that were not related at all.

TinEye provides an interesting service that might be useful for people who like to check if their images or photos are used on other websites. It might also be interesting for research and other purposes. The service is currently in beta stage.
