How do I get this code to work for an onmouseover and onmouseout event for an image? (I don't want it to be all over the page; just when I hover over an image)

Thanks!

I tried putting the <script> in the head section, and making a function called asdf(), and have that be called in the body, but it wouldn't work.

The current script has an image following it around the page:

<html>
<head>
<title>test</title>
</head>
<body>
asdf
asdf
asdf
<script type="text/javascript">

var trailimage=["mag_glass.gif", 50, 38] //image path, plus width and height
var offsetfrommouse=[-10,-15] //image x,y offsets from cursor position in pixels.

Enter 0,0 for no offset
var displayduration=0 //duration in seconds image should remain visible. 0 for

always.

if (displayduration>0)
setTimeout("hidetrail()", displayduration*1000)

document.onmousemove=followmouse

function gettrailobj(){
if (document.getElementById)
return document.getElementById("trailimageid").style
else if (document.all)
return document.all.trailimagid.style
}

function truebody(){
return (!window.opera && document.compatMode && document.compatMode!="BackCompat")?

document.documentElement : document.body
}

function hidetrail(){
gettrailobj().visibility="hidden"
document.onmousemove=""
}

function followmouse(e){
var xcoord=offsetfrommouse[0]
var ycoord=offsetfrommouse[1]
if (typeof e != "undefined"){
xcoord+=e.pageX
ycoord+=e.pageY

Here's an example, except I want it to happen only when it moves over an image:

I used this code instead, but thanks!

<html>
<head>
<style type="text/css">

#dhtmltooltip{
position: absolute;
border: 0px;
visibility: hidden;
z-index: 100;
}

#dhtmlpointer{
position:absolute;
z-index: 101;
visibility: hidden;
}

</style>
</head>
<body>
<script type="text/javascript">
