Interactive Image Slideshow add image button rollovers?

[dknric]

I'd like to add a rollover effect to the 'next.jpg' and 'back.jpg' images in the code below and still have the onClick work... any suggestions? I tried adding a rollover or onmouseover command but must be doing it wrong as it did not take. here is the code below

<input name="image" type="image" id="image" onClick="Prev();" src="images/back.jpg" alt="previous slide">
<input name="image" type="image" id="btnNext" onClick="Next();" src="images/next.jpg" alt="next slide">

I am using the following dynamic drive script below:

<script language="JavaScript1.2">

g_fPlayMode = 0;
g_iimg = -1;
g_imax = 0;
g_ImageTable = new Array();

function ChangeImage(fFwd)
{
if (fFwd)
{
if (++g_iimg==g_imax)
g_iimg=0;
}
else
{
if (g_iimg==0)
g_iimg=g_imax;
g_iimg--;
}
Update();
}

function getobject(obj){
if (document.getElementById)
return document.getElementById(obj)
else if (document.all)
return document.all[obj]
}

function Update(){
getobject("_Ath_Slide").src = g_ImageTable[g_iimg][0];
//getobject("_Ath_FileName").innerHTML = g_ImageTable[g_iimg][1];
//getobject("_Ath_Img_X").innerHTML = g_iimg + 1;
//getobject("_Ath_Img_N").innerHTML = g_imax;
}


function Play()
{
g_fPlayMode = !g_fPlayMode;
if (g_fPlayMode)
{
getobject("btnPrev").disabled = getobject("btnNext").disabled = true;
Next();
}
else
{
getobject("btnPrev").disabled = getobject("btnNext").disabled = false;

}
}
function OnImgLoad()
{
if (g_fPlayMode)
window.setTimeout("Tick()", g_dwTimeOutSec*1000);
}
function Tick()
{
if (g_fPlayMode)
Next();
}
function Prev()
{
ChangeImage(false);
}
function Next()
{
ChangeImage(true);
}


////configure below variables/////////////////////////////

//configure the below images and description to your own.
g_ImageTable[g_imax++] = new Array ("images/boys.jpg");
g_ImageTable[g_imax++] = new Array ("images/boys2.jpg");

g_ImageTable[g_imax++] = new Array ("images/girlndog.jpg");
g_ImageTable[g_imax++] = new Array ("images/boysfishing.jpg");
//extend the above list as desired
g_dwTimeOutSec=5

if (document.getElementById||document.all)
window.onload=Play
Next();
Play()

Thanks for anyone that can help... I'm not exactly experienced with this stuff.
