Design question

I don't really know what I am talking about when I ask this question but...

Does anyone know how to insert the emblem into the address bar?

If you were to go to google.com, there is a little emblem to the right of the url with the multi-colored "G" that is displayed whenever i visit the site.

Thanks

Hello SuperPhil,
That's easy once you know what it's called. Google favicon and you can find lots of step by step how-tos.
