Help Loading Image with XML

I am working on trying to get use an XML file to load information that is called upon. So far I was able to load the XML file and call out text and display in flash. I am having an issue getting actionscripts to grab the URL string from the XML of the image i want to use. I am having trouble with my imageLoader finding the URL. Maybe Im parsing it wrong? anyway below is the XML and attached is my AS3.
