Gen Borling,
My guess would be you don't have the right leader.bmp file in your info folder. If the oob points to a number outside the range of the file you have you don't get a picture. Suggest you try My Corinth Site at
http://home.comcast.net/~krmiller_cor/
the leaders.bmp file there is used in most of the mods out there.
Gen Bangma,
You probably have the wrong units.bmp file in your info folder. There are several of those out there and most of them didn't stick with the original picture locations. Another reason why my site was created. If you download one of the units.bmp for Corinth there and use teh oob's I have available the pictures will match ok.
