Image Swap Function on Rollover – Can you solve?!

Hi all. I have a map that I created which contains about 10 “poly” hotspots. These hotspots have image swap behavior to them. When I export the HTML code and paste into my WP page the behavior doesn’t follow.

I have copied the JS from dreamweaver and added this JS file into my site. I am successfully (I think) calling the script since when I hover over the test “pin” located at LA, I get a ‘javascript’; popup but the image doesn’t swap. Here is the code that I have in my js file:

<script language="JavaScript1.2" type="text/javascript">
<!--
function MM_findObj(n, d) { //v4.01
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
  if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
  var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
   if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
function MM_preloadImages() { //v3.0
  var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
    var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
    if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}

//-->
</script>

Here is my HTML code I am entering into my WP page (this is a shortened version with just one image swap function)

<onload="MM_preloadImages('http://recordyouradventures.com/test/wp-content/uploads/2012/08/Los-Angeles-CA.png','http://recordyouradventures.com/test/wp-content/uploads/2012/08/MAP-MASTER2.png');">

<img name="mapmaster2" src="http://recordyouradventures.com/test/wp-content/uploads/2012/08/MAP-MASTER2.png" width="973" height="664" border="0" id="mapmaster2" usemap="#mapmaster2" alt="" /><map name="mapmaster2" id="mapmaster2">
<area shape="poly" coords="87,405,90,398,92,392,87,387,82,384,71,388,71,396,68,405,68,420,70,426,77,426,87,405" href="javascript:;" alt="" onmouseout="MM_swapImage('mapmaster2','','http://recordyouradventures.com/test/wp-content/uploads/2012/08/MAP-MASTER2.png',1);"  onmouseover="MM_swapImage('mapmaster2','','http://recordyouradventures.com/test/wp-content/uploads/2012/08/Los-Angeles-CA.png',1);"  />

The map can be seen: http://www.recordyouradventures.com/test
Hover over the LA pin to see what does/doesn’t happen!

Any help would be greatly appreciated. Thank you!!
