The standard graphics approach now involves PaintShop Pro ( and
using it to convert the graphics to RAW or PGM(portable gray map)
format, then dealing with it.  I don't know if PaintShop Pro is
available for Nextstep, but I suspect it is not.  Barring that, you will
have to research the graphics format of the files you are interested in
and write your own routine.  Someone has done this for monochrome
bitmaps.  I can send you his code if you like.  You also might post your
problem to the suggestions at and suggest that they
incorporate  graphics file reading abilities into Mma.  I personally
think that in light of the cat picture on page 9 of the tour of
mathematica that it is  something close to false advertising that they
do not have graphics file reading abilities.
