Favicon

A favicon /ˈfævɪkɒn/ (short for Favorite icon), also known as a shortcut icon, Web site icon, URL icon, or bookmark icon, is a file containing one or more small icons, most commonly 16×16 pixels, associated with a particular Web site or Web page. A web designer can create such an icon and install it into a Web site (or Web page) 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 desktop icon.
