A favicon, which stands for favorite icon, is a small icon that is displayed in the address bar, next to the URL. With prior versions of Internet Explorer, the favicon was only visible when looking at your list of favorites. Now that it is displayed more prominently in IE7, it may be beneficial for your website to have one for use as a branding tool and to aid in site recognition.
Here are a few things to note regarding favicon creation / usage:
- 16x16 pixels with 16 colors
- Must be named favicon.ico (all lowercase)
- favicon.ico must be uploaded as Binary file (not ascii)
- Put the file in the main "www" directory
Images that do not meet these specifications may appear without a problem in some browsers; however, you must follow these guidelines to ensure that your favicon is displayed uniformly in all browsers.
