I can't import the edited BMP face file back into *.fsh file

I want to edit the cyberface of some of the players. Why is it that when I extract a face file in BMP format from *.fsh file and edit it in Photoshop, and then try to import it back in to the *.fsh, I get an error and I can't import? It must be something to do with the BMP file that I am trying to import. What graphics editor do you use and what format should I save it as before importing back into *.fsh? Thanks!!!

You are probably importing into a .viv within a .viv, check a topic in live 2004 announcements called "how to use Vivmagic" or something posted by lil_big_man.
