Ever wonder how websites get that cute little icon on the tool bar or on you favorites bar? Well wonder no more:
Add this to your HTML after the HEAD section (use whatever icon you want)
<link rel="icon" href="favicon.ico" type="image/x-icon">
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon">
This is how, for example, this forum gets the little weather scene as the icon in the toolbar.
