This is great to know. While I have downloaded/installed libtiff
(tiff-3.8.2.zip) on my UNIX server, I do not have tiffcrop installed as one
of the utilities.How can I configure/install this. Configure/make didn't
create this. I'm no developer, so need a bit of help if possible in getting
this set-up.

Thanks 

Robert
