Gosh...! I got no idea about this, and I'm in the repair-Poser-platform-blues business now for two years... Yes, on Mac you can select any readable/openable texture file when Poser asks for it, no matter where it sits, no matter how it's called, no matter which format - straight from Poser1-4 and (hopefully) 4.2 aka PPP. And I was perfectly sure that this is true for PC as well. Hmm.
