Google Images is a comprehensive image search tool, allowing users to quickly browse through a huge range of web images depending on what search term you have used.

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.
