A favicon, also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing a small icon associated with a particular website or web page. Browsers that provide favicon support typically display a page's favicon in the browser's address bar (sometimes in the history as well) 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.
Favicon is usually a small version of your logo. Please provide a file containing your logo or any other image you would like to use as a favicon and I will create an .ico file in 16x16, or 32x32 pixels size. It should be uploaded to the root folder of your website and named 'favicon.ico'.
