Advantages of using .ico over .png or .gif
It is suggested to avoid using .png or .gif instead of .ico file as your site favicon. Here are the main advantages of .ico file format:
- Compatibility - All browsers, including IE 5.0 support .ico format.
- Avoid 404 server errors - All modern browsers (tested with Chrome 4, Firefox 3.5, IE8, Opera 10 and Safari 4) will always request a favicon.ico so it's best to always have a favicon.ico file, to avoid a "404 not found" errors.
