How Do I Open a *.cps file?

A while ago, I received via e-mail some photos from a friend (of his fishing trip). Instead of being in a common format, say .jpg, .gif, .tiff or such, they’re in .cps format, which, according to sources I’ve already consulted is for “color post script” files. None of my programs seem to recognize it (not even Photoshop). Is there any universal viewer out there? A nifty translator? Tired of so-called experts, I’m turning to the folks who REALLY know thier stuff. Fellow Dopers, help me see my pal’s fish!

Illustrator would be the appropriate Adobe product to use, rather than Photoshop.

But if you just want to view it, you should be able to use Ghostscript.
