A favorite Icon is a small icon that displays next to the URL in the browser. This article contains information about adding Favorite Icon to your site.
Step 1 - creating the image
Using your favorite graphics software, create a 16x16 pixel image depicting your icon
Most web sites use a smaller version of their logo or similar
The main consideration is to keep your icon simple and clear at such a small size
It is also often important to use as few colors as possible
Most browser interfaces (the top toolbar containing the browser buttons) can display 256 colors, but it's best to use the Windows 16 colors
Save this image as favicon.bmp
It is important to save as .bmp format as some icon editors won't open .gif format graphics
Step 2 - creating the icon
Open up your icon editor and browse for your saved .bmp
When you open your .bmp to create an icon from it, make sure that you are using no more than 256 colors (IconForge gives you the option to choose how many colors) and preferably the Windows 16 colors
If necessary, edit the image
Save the image as an icon
Make sure it is called favicon.ico and now has the file extension .ico
Step 3 - including the icon in your web pages
Publish the icon into the root directory of your web site
This is where Internet Explorer will automatically look for it when a visitor bookmarks your site
Preferably nearer the closing tag, because more important information, such as your meta tags , should come earlier
Save your web page and publish it
If you want to create different icons for different pages , simply call them something other than favicon.ico, but still retaining the .ico suffix
Link to them in your pages in the same way as above, just changing the href location for the different icons
Step 4 - testing your icon
Open Internet Explorer (version 5 or above) and bookmark your page
Determine if your icon stands out from other bookmarked web sites with favorites icons
If necessary, re-edit your icon and publish it again
However, you will need to remove the bookmark (Favorites > Organize Favorites, select your bookmark and click "Delete") and delete your temporary Internet files and page history (Tools > Internet Options, tab "General" and click "Delete Files" under "Temporary Internet Files" and click "Clear History" under "History").
This may take a few minutes if you haven't done this recently
Close your browser and re-open it , bookmark your page again to check the new version of your icon
Repeat until you're satisfied your icon is suitably eye-catching
