It's a conflict with the overlib_mini.js script. It defines createPopup. So this statement from thumbnailviewer2.js which in Firefox usually would evaluate to false:
Code:
iefiltercapable: document.compatMode && window.createPopup? true : false, //Detect browser support for IE filters
evaluates to true. You may fix that by editing the thumbnailviewer2.js file in a plain text only editor like NotePad, replacing that single line with these:
Code:
//Detect browser support for IE filters:
iefiltercapable: false,
/*@cc_on @*/
/*@if(@_jscript_version >= 5)
iefiltercapable: document.compatMode && window.createPopup? true : false,
@end @*/
