XML will load in local SWF, but not in HTML

i’m trying to use an XML slideshow in my flash website. i’ve gotten the xml to load into a swf and show all the images just fine. then i loaded that swf into another swf (my website) and things are no longer fine. if i ‘preview movie’ everything still works, but when i open up the html file that i published from the website swf, the images don’t show up…

…any ideas?
