Yes, this is really a question for the PIL mailing list at image-sig at python.org

TIFF is not fully supported -- it rarely is, because TIFF is a huge sprawling
standard that actually encompasses a number of different image
standards under one name.

In any case, the fact that you are getting this message means that

1) PIL *is* installed, and 
2) PIL has a problem with the TIFF file

It may be due to lack of access to a needed shared object
(library).  For example, you'll get a similar message with PNG files
if the PNG library is not available.  Or it may be something not
supported by PIL at all.  But whatever it is, it's all internal to PIL,
not a Zope issue.

Cheers,
Terry
