Use map plugin as image map ?

Hi there,
I wondered wether it was possible to use the predefined map layer in the automatically generated vtourskin as an image map instead of bing or google ?
I tried just changing the url of the layer skin_map from bingmaps.swf to the url of the picture I want to use but it didn't work..Anyone suggestions what I could do instead ? Reason why I want to use the existing code is that it looks so great and I don't think I could integrate a map that well into the control bar myself.
Thanks in advance,
Flo
