Hi Rooster,
Just looking at my current pilots dossier, I would say no to your question, the dossier files doesnt refferance any pilot.bmp images at all.
I would say the manger is coded indipendantly of the dossier file to take pilot picture #1 and apply it to dossier # 1 etc.
Sooo, in your case I would take my #5 picture and rename it as #1 and vise versa, this will give you your desired picture in game for your current pilot.
HTH's
regards Rob.
just thought, if you like one certain pilot image you could make multiple copies of that image and name them 1, 2, 3, 4, 5, etc et c and you will get the same image for every pilot you enlist, until you reach the last one you made. ie #25
