Did you set "SelectPortrait" and "ButtonImage" to their corresponding names in the MappedImage?

For example:

MappedImage ChinaOfficer_lg
Texture = ChinaOfficer128x128.tga
TextureWidth = 128
TextureHeight = 128
Coords = Left:0 Top:0 Right:128 Bottom:128
Status = NONE
End
 
MappedImage ChinaOfficer_sm
Texture = ChinaOfficer64x64.tga
TextureWidth = 64
TextureHeight = 64
Coords = Left:0 Top:0 Right:64 Bottom:64
Status = NONE
End

Then your code would be:

; *** ART Parameters ***

  SelectPortrait         = ChinaOfficer_lg

  ButtonImage            = ChinaOfficer_sm
