Rollover Image Swaps

To add a rollover image, there are three elements you need to add to your layout file. First, add this line of code between the <head> tag:

<!--- Javascript for Image Swaps --->
<script type="text/JavaScript">
<!--
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
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];}}
}
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];}
}
//-->
</script>

     <script type="text/JavaScript">

          <!--

          function MM_swapImgRestore() { //v3.0

               var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;

          }

               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];

          }

          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];}

          }

          //-->

     </script>

Then, to preload the images that are not shown in the up state add this line as the <body> tag:

<!--- Preload the "on" buttons for Image Swaps --->

<body onload="MM_preloadImages('images/layouts/btn_events_on.jpg', 'images/layouts/btn_ministries_on.jpg', 'images/layouts/btn_resources_on.jpg', 'images/layouts/btn_visitor_info_on.jpg')">

Obviously replace the image paths with your own roll over (on) image states. Then, to call the actual image swap code, call the rollover image like this:

<a href="/index.cfm/PageID/1371/index.html" class="rollover" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('btn1','','images/layouts/btn_visitor_info_on.jpg',1)">

     <img src="images/layouts/btn_visitor_info_off.jpg" border="0" name="btn1" id="btn1" class="extra_nav">

</a>

Replace the link with your own as well as the rollover (on) image and up state (off) image.
