Website Icon

Internet Explorer ("IE") 5.0 and above has a facility where, if someone bookmarks your website (ie puts it in their "Favorites" menu), it associates a particular icon with your website in the bookmark. It tries to obtain that icon by first requesting for "favicon.ico" from the directory of your web page. If it cannot find such a file, it will try to obtain it from the root directory of your website, failing which, it will simply use a default icon for the bookmark.

Mozilla, and probably also the new versions of Netscape (which are based on Mozilla), also have the ability to use the favicon.ico file, except that Mozilla also accepts the file in other graphics formats, such as the PNG format. It displays the "favicon.ico" in the location bar of the browser (the part that shows your website's URL). The latest version of Opera also loads the favicon.ico file into the address bar if available.

How to Create a "Favicon.ico" File

1. Create an image 16X16 pixels in size. Yes, it is really small and you can't really draw much in it. You should also restrict yourself to the standard Windows 16 colours, although I suspect that 256 colours will work fine.
If you like, you can also create a 32X32 pixel icon, which will be scaled to size for the Favorites menu and the location bar. You can even put both 16X16 and 32X32 pixel icons into the same icon file. Windows will use the former for its menus and the latter when the user opens up a folder that is set to display large icons. It's probably not really necessary to do this if you can't be bothered.
2. Save the image as an ICO file (named "favicon.ico", of course).
3. Upload it to your website. You don't need to upload one to every directory of your site if you don't want to waste space - simply put it in your root directory and IE will apparently locate it eventually. You can also upload it into your images directory, but you will need to modify your web pages if you do. See later in this article for more information on this.
