SOLVED can't link to site from banner

[Stefan118]

Hello,

I want to place 3 banners on my forum.
The banners have to resize depending on the screen resolution of the user.
Choices are 1024x768 and 1280x1024.

This works all well.
But I also want to redirect the member to the website of the banner in an other screen.
I can't figure out how to do this.
I tried the usual <a href="................."> on different places but nothing works.

Who can help me?

I have placed the folowing script in the advertising area.

<script language="javascript" type="text/javascript" src="/templates/high_javascript.js">
<!--
//var iWidth = 0;
//var iHeight = 0;

//-->
</script>

<center>

<script type="text/Javascript">
<!--
/*initialization for IE! Leave this funtion after the body tag */
 /*if(!window.Width && document.body && document.body.offsetWidth)
  {
   //window.onresize = recal;
 	 //alert("line114!");
   Width = windowWidth();
   Height = windowHeight();
   //alert(Width + "<br>" + Height);
   //alert("width");
 }
 */
//-->
var iWidth, iHeight, sRes;
if (window.innerWidth != null) {
	//alert("first");
	iWidth = window.innerWidth;
	iHeight = window.innerHeight; 
}
else if (document.body.clientWidth != null) {
	//alert("second");
	iWidth = document.body.clientWidth;
	iHeight=document.body.clientHeight;
} 
else {
	//alert("third");
	}

var imgPath1 = "left.jpg";
var imgPath2 = "center.jpg";
var imgPath3 = "right.jpg";
var imgAlt = "Click here to go to the website of the sponsor.";


if (iWidth <= 1100) {
     document.write("<img src='/images/advertenties/" + imgPath1 + "' vspace='20' alt='" + imgAlt + "' width='190'>");
     document.write("&nbsp;&nbsp;");
     document.write("<img src='/images/advertenties/" + imgPath2 + "' vspace='20' alt='" + imgAlt + "' width='250'>");
     document.write("&nbsp;&nbsp;");
     document.write("<img src='/images/advertenties/" + imgPath3 + "' vspace='20' alt='" + imgAlt + "' width='190'>");
	}

else {
     document.write("<img src='/images/advertenties/" + imgPath1 + "' vspace='20' alt='" + imgAlt + "' width='250'>");
     document.write("&nbsp;&nbsp;&nbsp;&nbsp;");
     document.write("<img src='/images/advertenties/" + imgPath2 + "' vspace='20' alt='" + imgAlt + "' width='400'>");
     document.write("&nbsp;&nbsp;&nbsp;&nbsp;");
     document.write("<img src='/images/advertenties/" + imgPath3 + "' vspace='20' alt='" + imgAlt + "' width='250'>");
	}
