I have the following HTML code :

<BODY>

     <DIV Id="whoarewe" style="HEIGHT: 21px; LEFT: 5px; POSITION: absolute; TOP: 18px;

VISIBILITY: visible; WIDTH: 32px; Z-INDEX: 1">
       <IMG border="0" Name="whoarewe" src="static-ball2.gif">
     </DIV>
     
     
  <DIV Id="whoarewe2" Style="position:absolute; top: 16px; left: 42px; visible: visible;

z-index:1">
    <A Href="Whoarewe.htm" Target="main-frame"><IMG Name="whoarewe2" Src="swhoarewe2.gif"

Border="0" Valign="top"></A>
  </DIV>
     
     
<div id="portfolio" style="HEIGHT: 21px; LEFT: 5px; POSITION: absolute; TOP: 60px; VISIBILITY:

visible; WIDTH: 32px; Z-INDEX: 1">
       <IMG border="0" Name="portfolio" src="static-ball2.gif" >
</div>

  <DIV Id="portfolio2" Style="position:absolute; top: 59px; left: 40px; visibility: visible;

z-index:1">
    <A Href="portfolio.htm"  Target="main-frame">    
    <IMG Name="portfolio2" Src="sportfolio2.gif" Border="0" Valign="top"></A>
  </DIV>
       
     
<DIV id="core-competence" style="HEIGHT: 21px; LEFT: 5px; POSITION: absolute; TOP: 117px;

VISIBILITY: visible; WIDTH: 32px; Z-INDEX: 1">
       <IMG border="0" Name="core-competence" src="static-ball2.gif">
</DIV>
     
     <DIV Id="core-competence2" Style="position:absolute; top: 117px; left: 40px; visibility:

visible; z-index:1">
          <A Href="core-competence.htm" Target="main-frame"><IMG Name="core-competence2"

Src="score-competence2.gif" Border="0" Valign="top"></A>
     </DIV>

</BODY>    
     I want to write an onClick function for each of the anchor tags such that the src of the image embedded within the link that is currently  clicked is changed to "spinning-ball.gif" and the image-source of the last clicked link changes back to the original.

Example : If clicked Link A
            Link A : Image-source = spinning-ball.gif AND
          END IF
          IF clicked Link B
            Link A : Image-sorce = changes back to static-ball.gif AND
            Link B : Image-source = spinning-ball.gif
          END IF

Try this, quite close to what you want :

<html>
<head>
<script language="javascript">
var imgObj = null;
var openImg = new Image();
openImg.src="open.gif";
var closeImg = new Image();
closeImg.src="close.gif";

function changeImage(imgName){
     var newImgObj = document.images[imgName];
     if(newImgObj){
          if(imgObj) {
               if(imgObj != newImgObj){
                    imgObj.src = closeImg.src;
                    newImgObj.src= openImg.src;
               }
          }else{
               newImgObj.src= openImg.src;      
          }
     }
     imgObj = newImgObj;      
}
</script>
</head>
<body>
<img src="close.gif" name="position_id1"> <a href="javascript:void(0)" target="" onClick="changeImage('position_id1')">link 1</a>

<img src="close.gif" name="position_id2"> <a href="javascript:void(0)" target="" onClick="changeImage('position_id2')">link 2</a>

<img src="close.gif" name="position_id3"> <a href="javascript:void(0)" target="" onClick="changeImage('position_id3')">link 3</a>
</body>
</html>

Put this script in the head:

<script>
var activeOriginal="";
var active="";
function changeImgs(newImgName) {
  if (active) {
     active.src=activeOriginal;
  }
  if (document.all) {
    active=document.images[newImgName];
     activeOriginal=active.src;
    active.src="button.gif";
     return true
  }
  if (document.layers) {
    active=document.layers[newImgName].document.images[newImgName];
  }
  if (document.getElementById) {
    active=document.images[newImgName];
  }
  activeOriginal=active.src;
  active.src="button.gif";
  return true;
}
</script>

And in the links, put onclick="changeImgs('whoarewe2')" and so on for each link.

Of course this could be shorter still:
<script>
var activeOriginal="";
var active="";
function changeImgs(newImgName) {
 if (active) {
    active.src=activeOriginal;
 }
 if (document.all||document.getElementById) {
   active=document.images[newImgName];
 }
 if (document.layers) {
   active=document.layers[newImgName].document.images[newImgName];
 }
 activeOriginal=active.src;
 active.src="button.gif";
 return true;
}
</script>

<html>
<head>
<script language="javascript">
var count=0,c

function nothing()
{}

function abc(c)
{
if(c==1)
s1.src="still4.jpg"

if(c==2)
s2.src="still4.jpg"

if(c==3)
s3.src="still4.jpg"

if(count!=0)
{
if(count==1)
s1.src="still1.jpg"

if(count==2)
s2.src="still2.jpg"

if(count==3)
s3.src="still3.jpg"
}
count=c
}
</script>
</head>
<body>
 <a href="javascript:nothing()">
<img  id="s1" src="still1.jpg" onclick=abc(1) >
<a href="javascript:nothing()">
 <img id="s2" src="still2.jpg" onclick=abc(2)></a>
<a href="javascript:nothing()">
<img id="s3" src="still3.jpg" onclick=abc(3)></a>
</body>
</html>

Replace the still1,still2,still3 by the names of your image
still4 is the image that you want to have spinning-ball.gif in this case and any url in your anchor tag

May I please ask why you have your images in divs and absolutely positioned???
Makes it very hard to swap in all other browsers than IE...
Can't they just be in a table or even not in a table?


<BODY>
<IMG border="0" Name="whoarewe" vspace=5 hspace=5 src="static-ball2.gif"><A
Href="Whoarewe.htm" Target="main-frame"><IMG Name="whoarewe2" vspace=5 hspace=5
Src="swhoarewe2.gif" Border="0" Valign="top"></A><br>
<IMG border="0" Name="portfolio" vspace=5 hspace=5 src="static-ball2.gif" ><A
Href="portfolio.htm"  Target="main-frame"><IMG Name="portfolio2" vspace=5 hspace=5
Src="sportfolio2.gif" Border="0" Valign="top"></A><br>
<IMG border="0" Name="core-competence" vspace=5 hspace=5 src="static-ball2.gif"><A
Href="core-competence.htm" Target="main-frame"><IMG Name="core-competence2"
Src="score-competence2.gif" vspace=5 hspace=5 Border="0" Valign="top"></A>
</BODY>

yes this code does the trick:
<script>
var activeOriginal="";
var active="";
function changeImgs(newImgName) {
if (active) {
   active.src=activeOriginal;
}
if (document.all||document.getElementById) {
  active=document.images[newImgName];
}
if (document.layers) {
  active=document.layers[newImgName].document.images[newImgName];
}
activeOriginal=active.src;
active.src="spinning-ball.gif";
return true;
}
</script>

and in each link do like:
<A Href="Whoarewe.htm" Target="main-frame" onclick="changeImgs('whoarewe2')"><IMG Name="whoarewe2" Src="swhoarewe2.gif" Border="0" Valign="top"></A>

The parameter passed to the changeImgs function is the same as the name given to the div and image elements.
