Material / Image Research Lab (MIRL)

TinEye is a clever new search engine that does reverse searching to help you find duplicates or better copies of an image.  This means that you can upload the image you are looking for, or paste in the image URL, and it will find all other versions (duplicates and variations) of that image on the internet – no text searching involved.  You can find out more and watch a very helpful three minute tutorial here.
