Page not displaying correctly in Firefox, Chrome & Safari

Go to:
http://www.thebusinessfile.info/maps/miltonkeyneslocation.html
and click on Central Milton Keynes.
This will open displaymap.asp in a new window.
This page displays 3 iframes; the adverts, the map image and the map listing.
In IE8 the page displays as I want it to; a horizontal scroll bar appears under the image when it is required.
However, in the other browsers the image displays in a small fixed width frame with a scroll bar irrespective of page size.
The problem seems to be assigning a percentage width (80%) to the iFrame.
If I apply a fixed width then more of the image displays but the larger maps then can get covered by the listing section - and no scroll bar is available.
This can be viewed at http://www.mitre.net/maps/miltonkeyneslocation.html

The code for displaymap.asp is here with the database connection stuff removed:

<html>
<head>
<%Response.Write("<title>" & sMap & " in " & sLocation & "</title>")%>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<link href="../style.css" rel="stylesheet" type="text/css">
<style type="text/css">
<!--
#mapbanner {

#mapads {
      position: absolute;
      top: 70px;
      left: 5px;
      background-color: #DFECF9;

#mapimage {

<div id="mapads">&nbsp;</div>
<div id="mapimage">&nbsp;</div>
<div id="maptext">&nbsp;</div>
</div>
</body>
</html>

And for centremap.asp:

<html><head><title>Mitre Publications</title>
<link rel=stylesheet type=text/css href=../style.css>
<style type='text/css'>
</style>
</head>
<body bgcolor="#DFECF9">
<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" bgcolor="#DFECF9">
<tr><td bgcolor="#DFECF9"><div align="center"><img src="mapimages/<%= sGif %>" /></div></td>
</tr>
<tr><td></td>
</table>
</div>
</body>
</html>            
 
Would appreciate some help!

If you give the containing div(#mapimage) a width of 80% does that help?
