OK.  That's how it works now:

There are two hooks (maybe more to come) for now.

1. The 'onReady' hook.
   You may add functions to that hook using

   #+STYLE: <script type="text/javascript">
   #+STYLE: org_html_manager.onReady(function(){alert("Ready");});
   #+STYLE: </script>

   The hook is called with exactly one parameter: the OrgHtmlManager
   object (which is the first parameter for every hook function).


2. The 'onShowSection' hook.
   You may add functions to that hook using

   #+STYLE: <script type="text/javascript">
   #+STYLE: org_html_manager.onShowSection(function(ohm, obj){
   #+STYLE:     alert("Showing "+ohm.rT(obj.current.H.innerHTML));
   #+STYLE: });
   #+STYLE: </script>

   The hook is called with two parameters: the OrgHtmlManager
   object (which is the first parameter for every hook function) and an
   object

      {last: OrgNodeObject, current: OrgNodeObject}




You may add several functions to a hook by calling the `onReady' method
several times.  Fist added, first executed.



So you would just add your LightBox stuff like this (untested):


org_html_manager.onShowSection(function(ohm, secs)
{
    var imgs = secs.current.D.getElementsByTagName("img");
    for(var i=0;i<imgs.length;++i) {
	if(imgs[i].parentNode.tagName == "A" && imgs[i].parentNode.rel == "lightboxGrp") {
	    parent = imgs[i].parentNode.parentNode;
	    div_id = "";
	    do {
		if(parent.tagName == "BODY") {
		    div_id = "NaN_body";
		}
		else if(parent.tagName == "DIV" && parent.className == "outline-text-2") {
		    div_id = parent.id;
		}
		else {
		    nxtParent = parent.parentNode;
		    parent = nxtParent;
		}
	    } while (div_id == "");
	    imgs[i].parentNode.rel = "lightbox["+div_id+"]";
	}
}




Best wishes
