Definition: A thumbnail is a small image, or a part of a larger image. Normally a thumbnail will be of a border background, or a background set, or a photograph. Clicking on the thumbnail image will pull up the larger original image, which can be viewed and downloaded. Using thumbnails of background sets, borders, and photographs allows more than one or two images to be shown on a Web page.
