// Displays rotating banner adverts for <img> tags, named
// adbanner+number. Cycles through tags every 15 seconds
// assigning next image and alt text to the <img> tag and
// the url to a <a> tag named adlink+number. Starts from
// a random image in the sequence.
// This script must be included after the banner tags.
// e.g.
// <a href="url1" id="adLink1" target="_top">
// <img src="imgurl1" id="adBanner1" border="0" width="150" height="75"></a>
// <script type="text/javascript" language="JavaScript" src="adrotator.js"></script>
