Just for design pleasure, but also because it is very convenient.
Maybe it could also be good to add it in this forum Jaben.
The idea is just to have a little icon of your choice that appears left of the address bar and when you develop your navigation bar.
This way the user can easily recognize your adress and click it. This does not work with Internet Explorer which puts its own icon everywhere...
In your main page, just add the following code into the <head>:
<link rel="icon" type="image/jpg" href="images/SM_javicon.jpg">
Your image can have another format that .jpg, but I know that not all work: if you have a .gif, change type to "image/gif".
Your image must be 16x16 or 32x32 pixels.
In my example the name of my icon is 'SM_favicon', and I put it within the YAF images folder.
