CodingForums.com - Calling jQuerys lightbox from function

I am trying to launch jQuerys lightbox via a function called by flash. Example:http://www.campbelltest.co.uk/britis...ueryFinal.html

I previous had this working with Lightbox2 by Lokesh Dhakar using the function below:

Code:

function openLightbox(url,group){

        trace("url"+ url)

        var objLink = document.createElement('a');

        objLink.setAttribute('href',url);

        objLink.setAttribute('rel','lightbox['+group+']');

        objLink.setAttribute('title','caption');

        Lightbox.(objLink);

}

Now I'm trying to make it work with jQuery Lightbox Plugin (balupton edition). I have modified my code to the below to try and launch the light box but without any success.

Code:

function openLightbox(url,group){

        var objLink = document.createElement('a');

        objLink.setAttribute('href',url);

        objLink.setAttribute('rel','lightbox['+group+']');

        objLink.setAttribute('title','caption');

        jQuery.Lightbox.init(objLink)

};

I have setup two trace commands on the init function to monitor what is happening when the function is called using http://v2.easy-designs.net/code/jsTrace/. When you click one of the static links on the bottom of my examples page the trace command returns the variables:
image=http://www.campbelltest.co.uk/britishMuseum/online/images/image-statue.jpg
images=[object Object]

To get flash to call the function you have to click one of the 'enlarge image' buttons, one of which can found if you navigate in the flash to '2 Outer room - central view'>'A. Offering for Nebamun'. The trace function on the two variables comes back as
image=http://www.campbelltest.co.uk/britishMuseum/online/images/image-offering.jpg
images=undefined

Does anyone have an idea of how I should be calling this function or if I'm on the wrong track??

Thanks in advance,
