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 the web browsers that support favicons
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.Help! My Web Host Doesn’t Allow ICO Files!
If your hosting company does not allow files with the .ICO extension
to be uploaded,you might try to work around it by uploading it (in
binary mode) with some other extension (like GIF). Once it’s on your
site,rename it using your FTP program to the correct extension.
