If you download a mod from the database then the bmp's should not need renumbering at all .Just stick the in you bmp folder as is.
That is unless there is an option for markings or some thing.If its one of my mods i will always make a note of this in the read me.
In my case it will always be something along the lines of remove the S from the optional bmp no ie 12345S.bmp
But if there is no read me then look at the optional bmps (lets say a turret side with markings on )and find the same bmp that has no markings on and rename it the same as that one.
