TinEye and Search by Image (by Google)
Long before Google announced its Search by Image service -- where you drag a picture onto the Google search page, and it finds similar pictures -- there was TinEye, an innovative reverse image search service based in Toronto. Both product scan billions of images for matches and near-matches. Both now include the ability to right-click on an image inside your web browser and choose “Search image.” But they give very different results, with neither being superior to the other in all circumstances. Why not install both? They play very well together, and it only takes two right-clicks to get the best of both ocular search worlds.
