function ShowBanner() {

num = Math.random();
num = 1 + ( num * ((bannerpics.length - 1)-1));
num = Math.round(num);

document.write("<div><a href='" + bannerurls[num] + "'>");
document.write("<img src='" + bannerpics[num] + "' border='0' ");
document.write("alt='Click here to find out more!'>");
document.write("</a></div>");

document.write("<div onClick=\42window.open('"+bannerurls[num]+"','banner','menubar=yes,location=yes,status=yes,toolbar=yes,scrollbars=yes');\42");
document.write("<img src='" + bannerpics[num] + "' border='0' ");
document.write("alt='Click here to find out more!'>");
document.write("</div>");

document.write("<div><a href='" + bannerurls[num] + "' target='_blank'>");
document.write("<img src='" + bannerpics[num] + "' border='0' ");
document.write("alt='Click here to find out more!'>");
document.write("</a></div>");
