[Zope] images are not found when zope is server through IIS

hello, before I bang me head to figure out what is happening, I wonder if one of you has this problem: Zope is running on Windows NT with pcgi through IIS. I use the LocalFS product to serve images. http://mysite.com/Zope.pcgi/FS/photo.gif doesn't work: photo.gif is not found. however, http://mysite.com:8080/FS/photo.gif works as expected: the image is found and displayed correctly. Note that this seems not to be related to the LocalFS product, as no images are shown in the management screens, they are not found neither. the funny part is this problem only occurs for images. All other objects (methods, documents, etc...) are always found Any ideas? regards, Jephte CLAIN
