scriptkonflikt og tabeller

Jeg har to scripts der er i konflikt med hinanden.

De ser således ud:

<script type="text/javascript">

/****************************************************
*            DOM Image rollover:
*        by Chris Poole
*        http://chrispoole.com
*              Script featured on http://www.dynamicdrive.com

****************************************************/

function init() {
  if (!document.getElementById) return
  var imgOriginSrc;
  var imgTemp = new Array();
  var imgarr = document.getElementsByTagName('img');
  for (var i = 0; i < imgarr.length; i++) {
    if (imgarr[i].getAttribute('hsrc')) {
        imgTemp[i] = new Image();
        imgTemp[i].src = imgarr[i].getAttribute('hsrc');
        imgarr[i].onmouseover = function() {
            imgOriginSrc = this.getAttribute('src');
            this.setAttribute('src',this.getAttribute('hsrc'))
        }
        imgarr[i].onmouseout = function() {
            this.setAttribute('src',imgOriginSrc)
        }
    }
  }
}
onload=init;

</script>

var content=new Array()
//change the array below to the text associated with your links Expand or contract the array, depending on how many links you have
content[0]='<big><b>valg 1</b></big><br>bla bla bla '
content[1]='<big><b>valg 2</b></big><br>yada yada yada'
content[2]='<big><b>valg 3</b></big><br>tra la la la la'

function regenerate(){
window.location.reload()
}
function regenerate2(){
if (document.layers){
appear()
setTimeout("window.onresize=regenerate",450)
}
}

function changetext(whichcontent){

if (document.all||document.getElementById){
cross_el=document.getElementById? document.getElementById("descriptions"):document.all.descriptions
cross_el.innerHTML='<font face="Tahoma"><small>'+whichcontent+'<font></small>'
}
else if (document.layers){
document.d1.document.d2.document.write('<font face="Tahoma"><small>'+whichcontent+'</small></font>')
document.d1.document.d2.document.close()
}

}

function appear(){
document.d1.visibility='show'
}

window.onload=regenerate2


//-->
</script>


Det sidste script skal egentlig KUN fungere i en af to tabeller på en side.

Mit spørgsmål er så:
Kan jeg definere at det ene script KUN skal gælde for en del af siden, og i så fald, hvordan?
ELLER... er der en anden løsning på problemet?
