Image icon beside the site URL
What is currently the best way to get a favicon to display in all browsers that support Favicons?
I want to add my logo in the address bar of the browser, whenever it is browsed.
How do I make a favicon?
You need a favicon - this is a 16x16 image in .ico format stored as favicon.ico in the root directory your site. Some browsers do support other formats too.
A newer, more standards based approach is to include something like this in your html head:
<link rel="icon" type="image/png" href="/path/image.png"/>
