Thumbshots are screenshots of online documents such as web page in small thumbnail sizes. Thumbshots help users to visualize web sites or preview links before clicking. The dimension of a thumbshot image (usually under 120 pixels in width by 90 pixels in height) is generally much smaller than the actual online document allowing users to download and view a sample of the document quickly. Thumbshots can be automatically generated by custom software or manually screen captured using popular graphics programs. [1]

Thumbnail reduced-size versions of pictures or videos

Thumbnails are reduced-size versions of pictures or videos, used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words. In the age of digital images, visual search engines and image-organizing programs normally use thumbnails, as do most modern operating systems or desktop environments, such as Microsoft Windows, macOS, KDE (Linux) and GNOME (Linux).

Image artifact that depicts or records visual perception

An image is an artifact that depicts visual perception, such as a photograph or other two-dimensional picture, that resembles a subject—usually a physical object—and thus provides a depiction of it. In the context of signal processing, an image is a distributed amplitude of color(s).

Some thumbshot pictures are enhanced with informative icons or text highlights. Normally, thumbshots are found embedded inline beside hyperlinks in a web page to help improve web browser navigation by helping users to locate information faster. Thumbshots are often used to provide visual hints in search engines and web directories where a large number of text links are displayed on a page.

Web browser software application for retrieving, presenting and traversing information resources on the World Wide Web

A web browser is a software application for accessing information on the World Wide Web. Each individual web page, image, and video is identified by a distinct URL, enabling browsers to retrieve and display them on the user's device.

One of the early applications of thumbshots was developed by Jakob Nielsen while working for Sun Microsystems. The application consisted of capturing and then displaying a small image of a webpage that a user had saved as a bookmark in their web browser. At that time, they were referred to as visual bookmarks.

A web directory or link directory is an online list or catalog of websites. That is, it is a directory on the World Wide Web of the World Wide Web. Historically, directories typically listed entries on people or businesses, and their contact information; such directories are still in use today. A web directory includes entries about websites, including links to those websites, organized into categories and subcategories. Besides a link, each entry may include the title of the website, and a description of its contents. In most web directories, the entries are about whole websites, rather than individual pages within them. Websites are often limited to inclusion in only a few categories.

A favicon, also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing one or more small icons, associated with a particular website or web page. A web designer can create such an icon and upload it to a website by several means, and graphical web browsers will then make use of it. Browsers that provide favicon support typically display a page's favicon in the browser's address bar and next to the page's name in a list of bookmarks. Browsers that support a tabbed document interface typically show a page's favicon next to the page's title on the tab, and site-specific browsers use the favicon as a desktop icon.
