Yes.  16 modem line beast.

On the machine or after it's been emailed if you use that?

Try the tiffcheck program that comes with Hylafax.  It tells 
you if the .tiff is faxable.  If it's faxable, then it's readable.
man tiffcheck for more info.  You could also try tiffdump.

See (under the hylafx dir) bin/faxrcvd
TIFF2PS=tiff2ps
PS2PDF=ps2pdf
#
# Permit various types of attachment types: ps, tif, pdf
# Note that non-ASCII filetypes require metamail.
# pdf requires tiff2ps and ps2pdf
#
FILETYPE=ps


Or if the tiff is valid and it's just your viewer, ImageMagick
has a program that converts tiffs to just about any image 
format you want
