TinEye is an image search engine but it is not a regular image search engine, it’s new, different and unique. You can search images with an image.
TinEye is an image search engine built by Idée. You just simply upload your own image using their upload box or just put the Url of the image then TinEye will search images that similar to your image and TinEye will show you where the image appears on the web.
The feature that I like about TinEye is it can search even that image has been retouch, really cool.
TinEye is currently in beta version, you need to request an invite before you can try TinEye.
