Google Images

Google Images is a search service created by Google and introduced in July 2001, that allows users to search the Web for image content. The keywords for the image search are based on the filename of the image, the link text pointing to the image, and text adjacent to the image. When searching for an image, a thumbnail of each matching image is displayed. When the user clicks on a thumbnail, the image is displayed in a box over the website that it came from.
