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 wolfram.com 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.
