the download.php "might" not work on your server because you have the picture files outside of the main gallery folder. This is a server security setting that may apply.
I also see you have some weird setting in your sourcecode:
so.addVariable("globalpath", "&textcol=EFEFEF&configfile=config.ini&");
That value for globalpath certainly doesnt make sense. May I also ask why you want to keep your imagesfolders outside of the imagevue gallery folder? It would be better if you placed the entire gallery folder in your desired position, and simply integrated the entire imagevue.swf from a remote location to your html files using the globalpath parameter.
