Default Adding to this Javascript for image rollover show/hide

Hey everyone. I'm trying to add a little something additional to this script. This is a great script I found that shows a full size image in a separate div during rollover of thumbnail in different div.

What I would like to do is make an addition to this script that will allow me to load text, on the same mouse over, into another separate div below the full size picture load div (for this example, called photoload).

Any help or suggestions would be greatly appreciated.

Code:
var thumbnailviewer2={
enableTitle: true, //Should "title" attribute of link be used as description?
enableTransition: true, //Enable fading transition in IE?
hideimgmouseout: false, //Hide enlarged image when mouse moves out of anchor link? (if enlarged image is hyperlinked, always set to false!)

/////////////No need to edit beyond here/////////////////////////

iefilterstring: 'progid:DXImageTransform.Microsoft.GradientWipe(GradientSize=1.0 Duration=0.7)', //IE specific multimedia filter string
iefiltercapable: document.compatMode && window.createPopup? true : false, //Detect browser support for IE filters
preloadedimages:[], //array to preload enlarged images (ones set to display "onmouseover"
targetlinks:[], //array to hold participating links (those with rel="enlargeimage:initType")
alreadyrunflag: false, //flag to indicate whether init() function has been run already come window.onload

loadimage:function(linkobj){
var imagepath=linkobj.getAttribute("href") //Get URL to enlarged image
var showcontainer=document.getElementById(linkobj.getAttribute("rev").split("::")[0]) //Reference container on page to show enlarged image in
var dest=linkobj.getAttribute("rev").split("::")[1] //Get URL enlarged image should be linked to, if any
var description=(thumbnailviewer2.enableTitle && linkobj.getAttribute("title"))? linkobj.getAttribute("title") : "" //Get title attr
var imageHTML='<img src="'+imagepath+'" style="border-width: 0" />' //Construct HTML for enlarged image
if (typeof dest!="undefined") //Hyperlink the enlarged image?
imageHTML='<a href="'+dest+'">'+imageHTML+'</a>'
if (description!="") //Use title attr of the link as description?
imageHTML+='<br />'+description
if (this.iefiltercapable){ //Is this an IE browser that supports filters?
showcontainer.style.filter=this.iefilterstring
showcontainer.filters[0].Apply()
}
showcontainer.innerHTML=imageHTML
this.featureImage=showcontainer.getElementsByTagName("img")[0] //Reference enlarged image itself
this.featureImage.onload=function(){ //When enlarged image has completely loaded
if (thumbnailviewer2.iefiltercapable) //Is this an IE browser that supports filters?
showcontainer.filters[0].Play()
}
this.featureImage.onerror=function(){ //If an error has occurred while loading the image to show
if (thumbnailviewer2.iefiltercapable) //Is this an IE browser that supports filters?
showcontainer.filters[0].Stop()
}
},

hideimage:function(linkobj){
var showcontainer=document.getElementById(linkobj.getAttribute("rev").split("::")[0]) //Reference container on page to show enlarged image in
showcontainer.innerHTML=""
},


cleanup:function(){ //Clean up routine on page unload
if (this.featureImage){this.featureImage.onload=null; this.featureImage.onerror=null; this.featureImage=null}
this.showcontainer=null
for (var i=0; i<this.targetlinks.length; i++){
this.targetlinks[i].onclick=null
this.targetlinks[i].onmouseover=null
this.targetlinks[i].onmouseout=null
}
},

addEvent:function(target, functionref, tasktype){ //assign a function to execute to an event handler (ie: onunload)
var tasktype=(window.addEventListener)? tasktype : "on"+tasktype
if (target.addEventListener)
target.addEventListener(tasktype, functionref, false)
else if (target.attachEvent)
target.attachEvent(tasktype, functionref)
},

init:function(){ //Initialize thumbnail viewer script
this.iefiltercapable=(this.iefiltercapable && this.enableTransition) //True or false: IE filters supported and is enabled by user
var pagelinks=document.getElementsByTagName("a")
for (var i=0; i<pagelinks.length; i++){ //BEGIN FOR LOOP
if (pagelinks[i].getAttribute("rel") && /enlargeimage:/i.test(pagelinks[i].getAttribute("rel"))){ //Begin if statement: Test for rel="enlargeimage"
var initType=pagelinks[i].getAttribute("rel").split("::")[1] //Get display type of enlarged image ("click" or "mouseover")
if (initType=="mouseover"){ //If type is "mouseover", preload the enlarged image for quicker display
this.preloadedimages[this.preloadedimages.length]=new Image()
this.preloadedimages[this.preloadedimages.length-1].src=pagelinks[i].href
pagelinks[i]["onclick"]=function(){ //Cancel default click action
return false
}
}
pagelinks[i]["on"+initType]=function(){ //Load enlarged image based on the specified display type (event)
thumbnailviewer2.loadimage(this) //Load image
return false
}
if (this.hideimgmouseout)
pagelinks[i]["onmouseout"]=function(){
thumbnailviewer2.hideimage(this)
}
this.targetlinks[this.targetlinks.length]=pagelinks[i] //store reference to target link
} //end if statement
} //END FOR LOOP


} //END init() function

}


if (document.addEventListener) //Take advantage of "DOMContentLoaded" event in select Mozilla/ Opera browsers for faster init
thumbnailviewer2.addEvent(document, function(){thumbnailviewer2.alreadyrunflag=1; thumbnailviewer2.init()}, "DOMContentLoaded") //Initialize script on page load
else if (document.all && document.getElementsByTagName("a").length>0){ //Take advantage of "defer" attr inside SCRIPT tag in IE for instant init
thumbnailviewer2.alreadyrunflag=1
thumbnailviewer2.init()
}
thumbnailviewer2.addEvent(window, function(){if (!thumbnailviewer2.alreadyrunflag) thumbnailviewer2.init()}, "load") //Default init method: window.onload
thumbnailviewer2.addEvent(window, function(){thumbnailviewer2.cleanup()}, "unload")

Code:
<div class="thumbs">
  <a href="img/websites/aaa.jpg" alt="aaa" rel="enlargeimage::mouseover" rev="photoload">
    <img src="img/websites/aaa-tn.jpg" alt="aaa-tn" />
