to get the full idea of the desired effect, quickly vist this link
http://www.sonsofmaxwell.com/en/viewGallery.php?eid=6.

notice that when each thumbnail is clicked, the main image is replaced
by the thumbnail.

here is the JS code that triggers that effect:

function errorsuppressor(){
                return true
}

window.onerror=errorsuppressor

function MM_openBrWindow(theURL,winName,features) { //v2.0
  window.open(theURL,winName,features);
}

function showPic (whichpic) {
 if (document.getElementById) {
  document.getElementById('placeholder').src = whichpic.href;
  if (whichpic.title) {
   document.getElementById('desc').childNodes[0].nodeValue =
whichpic.title;
  } else {
   document.getElementById('desc').childNodes[0].nodeValue =
whichpic.childNodes[0].nodeValue;
  }
  return false;
 } else {
  return true;
 }
}

Now, i transferred this over to cake, and placed in my necessary
attributes.
<img src="someimage.jpeg" id="placeholder" />
<li><?php echo $html->link($html->image('inv/'. $photo['img'],
array('width' => '180px')), '/img/inv/'. $photo['img'],
array('onClick' => 'return showPic(this)', 'title' => 'Gary Dunham'),
false, false); ?></li>

which gives me the onclick attribute i need to trigger the image.  the
image swaps, but also points to a link similar as
http://localhost/garydunhamequipment/img/inv/gary_dunham_ver2.gif in
the browser.  i just want it to swap like it did in the above
example.  i am wondering, is there something possibly different about
the headers generated by a cake app that is causing this?
