It's known as a favicon and basically its an images which measures 16x16 pixels. The image is saved with the extension .ico. You can get some free programs for making these or if you have photoshop there is a free plugin which allows you to save one. I'm also quite sure that you can just save it as a .gif image and just change the extension to .ico. (best way is to use a program which does it though). After you have made you 16x16 px .ico image you need to insert the following code into the head of your HTML. <link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" /> Code (markup): This should work fine for you.
