hey bryan,
sorry i got sidetracked away from this. i do remember giving it another look and being convinced it still was a path issue compounded by your CMS
if you want to experiment further, you can download this zipped folder, which contains a swf, an xml file, web files ( both an html and a php file ) and a folder of images.
its all quite simple, as it is best to keep it simple when troubleshooting. the swf though is populated with 4 different fields from the xml: 2 text fields, one list box, and one image ( once a list item is choosen). It will 'prove' that it can access all the nodes of the xml file, AND retrieve from inside an images folder.
you can see it in action
here
and download the folder

i suggest you upload all the files, along with the image folder, to your sever, placing them all in the same directory, and then try to access the web page. let me know if it shows up and accesses the xml correctly, so we can take it from there
