Google Image Search Update
Google has quietly rolled out some really interesting features in their image search:
When users search for images they will notice a little camera icon in the search box. By clicking on that two options are given: a) Paste image URL and b) Upload an image. By telling Google what type of image you want to base your visual search on will help them refine the results better. Now in the image search users can see a little label with an image icon such as the one illustrated in the third example, including the visually similar images and thumbnails next to search results.
