Help with fitting logo to other resolutions

[Stefan118]

I used this on my ads.
This script is for resolution under 1100 pixels <> (1024x768)
and for a resolution above 1100 pixels <> (1280x1024)

It eighter places a banner with a width of 350 or 430 pixels.

<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 imgPath = "banner.jpg";
var imgAlt = "Alt text.";

if (iWidth <= 1100) {
     document.write("<a href=http://www.google.comenter a site url target=_new><img src='enter image sourcepath WITHOUT image name!" + imgPath + "' alt='" + imgAlt + "' width='350'></a>");

	}

else

 {
     document.write("<a href=http://www.google.com target=_new><img src='enter image sourcepath WITHOUT image name!" + imgPath + "' alt='" + imgAlt + "' width='430'></a>");
  }
