If you’ve tried a Google image search over the past week, you might have noticed some changes. Google recently launched a “new dense tiled layout,” with larger thumbnails and the ability to scroll through up to 1,000 images on a single page. If you click on a thumbnail, you’re now brought to a “hover pane,” showing the image as it “hovers” above the original website (and thus how the image might look in its original context).
There are other less visible changes, too: more sophisticated technology powers both the “similar images” tool and “similar colors” tool. You can read more about these changes on the Official Google Blog.
