Firefox not displaying CSS formatting - very confused

Hello everybody. I would appreciate it if somebody who has both Firefox and Internet Explorer installed could take a look at this page I am designing.

http://www.sjf.com/working/css/carousel.html

In IE it works just like I would like it to, however when I try and load it in Firefox, it doesn't seem to recognize that there is a stylesheet to load.

I am using StyleMaster to do the bulk of the CSS editing and the other strange issue I am having is thus: When I load it in Firefox directly from StyleMaster I get the styles to load correctly except the <img> links. They show up as a box underneath the bottom of the "sample.jpg" thumbnails.

Please let me know if you need any more information. I will be checking back here several times today. Thank you for your help.
