How can I get my logo appear as a bookmark icon?
All you need to do is save a small icon, sized 16 × 16, in the root folder, and call it favicon.ico. You can also have a unique icon for individual pages. Just put this in the <head> of the particular file, and point the URL to the location of the *.ico file you want to use:
<link rel="shortcut icon" href="http://www.example.com/anothericon.ico">
Originally, this was only supported by Internet Explorer 5.0 and above running on Windows, but it has since been picked up by browsers based on Mozilla 0.9.6 or higher on all platforms. This suggests Netscape 6.x will soon support them as well. Ironically, Mozilla’s support works better than Internet Explorer’s.
There are a number of tools out there for creating icons, but Favicon.com is dedicated to creating them—it even has an online icon-making tool.
