Question about Photo Slideshow using XML and Flash tutorial

I have a quesion concerning this tutorial located at
[font=Arial]http://www.kirupa.com/developer/mx2004/xml_slideshow.htm [/font][url=“http://www.kirupa.com/developer/mx2…l_slideshow.htm.”]. When I tried to point my url to different images at a different url, they didn’t show up. The images I was using are siginificantly smaller than the ones kirupa used but nonetheless they should still show up right? From looking at the code I didn’t see really any place that checked for size so not sure why I can’t see my images.
