A favicon (short for favorite icon), is a small icon (in ico format). It can be added to a web page. Most web browsers will display it on the address bar next to the URL. If a browser also supports a tabbed document interface, it may also show it next to the title of the page. See the example below which shows the favicon of our website (circled with red).
Favicon can be added to the template page or a normal web page. If it is added to a template page, any normal web page that uses the template page will show that favicon. Select Edit -> Page -> Page Properties from the main menu or right click on the page to select "Page Properties" from the context menu. Use either one of the following dialogs to select your icon. Which dialog is shown will depend on whether the page is a template.
