More information on favicon (favorites icon)
A favicon 
is a small, 16x16 image that is shown inside the browser's location bar(address bar) and bookmark menu when your site is called up. It is a good way to brand your site and increase it's prominence in your visitor's bookmark menu.
After you've created a neat favicon, it's time to add it to your site. To do so, follow the below simple procedure:
- Upload the generated file ("favicon.ico") to your site. Verify it's there by typing http://mysite.com/favicon.ico in the browser's location, where "mysite.com" is your site's address.
- Next, insert the below code in the HEAD section of your pages, at the very
least, your site's main index page:
<link rel="shortcut icon" type="image/x-icon" href="/favicon.ico">
- That's it! Note that your favicon may not appear immediately after you've completed the above two steps. You may need to refresh a few times.
