This is how an image link works (the a href= part is the site you are linking to when the banner is clicked):
<a href="http://www.website.com" target="_blank" ><img src="http://www.website.com/Banner%201.jpg" border="0" width="468" height="60" alt="a website"></a> | <a href="http://www.website.com" target="_blank"><img src="http://www.website.com/forums/images/misc/HighQual_blueHue.jpg" border="0" width="468" height="60" alt="another website"></a> | <a href="http://www.website.com" target="_blank"><img src="http://www.website.com/images/banner1.gif" alt="third website" width="468" height="60" border="0"></a>
Mine still doesn't autorefresh btw
