With \includegraphics, the referenced number will be reused,
if the first page is embeded later. Or only other pages
are used, or the pdf file will not embedded at all. So the
question is, what is the best strategy for getting the
number of pages?

Yes :-) (But somehow Andreas has to get number of pages--therefore
        the question above.)
