Well, here's my suggestion, and it's the same suggestion I offer to almost every Poser script out there. Tell us what its purpose is. You've told us what it does - it sets the U/V_Scale of image maps in the current figure/actor -  but that's a different thing from what its purpose is. What problem does it solve? In MBA parlance, what pain does it address? Why would someone want to use it?

There was an old Saturday Night Live skit that started with, "How many times have you coughed up a piece of lung and had no place to store it?" (It was a commercial for Playmate coolers.) A silly example, I guess, but that's how products are sold. You don't sell coolers by saying, "Playmate coolers insulate their contents by surrounding it with materials that don't allow the heat exchange... " You start with some kind of "don't you hate it when" statement.

I know I'm going on and on about this, but I see so many scripts out there that someone has put hours and hours into, but they never get used because the potential users have no clue as to why they would want to use them. 

Sorry I can't be more helpful about the script per se. It looks impressive, though.
