Pretty Photo Set linking Issues

Question

Hello,

Yesterday a nice stack overflow user helped me to trigger the Jquery Prettyphoto Lightbox from a DIV element rather than an A element.

You can find that solution here

This works... Almost.

Pretty Photo looks for all the links that reference it and then compiles them into a slideshow of iframes. Normally when you click on a link it will open up the iframe lightbox corresponding to the link i clicked on.

However with this new DIV solution it is opening up to the first iframe link it finds on the page, rather than the link I click on.

This must obviously be happening because I have altered the javascript call code from

<script type="text/javascript" charset="utf-8">
 $(document).ready(function(){
  $("a[rel^='prettyPhoto[iframes]']").prettyPhoto();
 });
</script>

to

<script type="text/javascript" charset="utf-8">
 $(document).ready(function(){
  $("div[class^='prettyphoto[iframes]']").prettyPhoto();
 });
</script>

I have been going through the other JS files but I am not a javascript programmer.

I am going to post the entire JS file. Maybe someone can see what javascript I need to change to make this DIV element work like an A element.

(function($) {
$.prettyPhoto = {version: '2.5.4'};

$.fn.prettyPhoto = function(settings) {
 settings = jQuery.extend({
  animationSpeed: 'normal', /* fast/slow/normal */
  padding: 40, /* padding for each side of the picture */
  opacity: 0.80, /* Value between 0 and 1 */
  showTitle: true, /* true/false */
  allowresize: true, /* true/false */
  counter_separator_label: '/', /* The separator for the gallery counter 1 "of" 2 */
  theme: 'light_rounded', /* light_rounded / dark_rounded / light_square / dark_square */
  hideflash: false, /* Hides all the flash object on a page, set to TRUE if flash appears over prettyPhoto */
  modal: false, /* If set to true, only the close button will close the window */
  changepicturecallback: function(){}, /* Called everytime an item is shown/changed */
  callback: function(){} /* Called when prettyPhoto is closed */

All help is appreciated.

It looks like the pretty photos code is using the rel attribute explicitly, do your div's have rel? You are calling the code on $("div[class^='menuitem[iframes]']").prettyPhoto();

But then pretty photos is looking for theRel = $(this).attr('rel'); and running against that.
