An important note: the number of possible pilot pics MAY be fixed by WOFF,
so when you add higher numbers like "Pilot101.bmp", this picture may not appear.

I suggest to replace original WOFF pilot photos with your own giving them the same number, like "Pilot3.bmp".

Make sure you name the original "Pilot3" into "PilotC" or whatever, or move him into a backup folder,
so that you can "re-activate" him later, if you wanted.
