Race Select Portrait Defines

So as the title says does anyone know where the value such as below is defined

leftPlayerPortraitBrush "RaceSelectDialogTechLoyalistPortrait"
leftPlayerPortraitArea [174,52,195,219]
rightPlayerPortraitBrush "RaceSelectDialogTechRebelPortrait"

I can Change the above to the below

leftPlayerPortraitBrush "RaceSelectDialogPsiLoyalistPortrait"
leftPlayerPortraitArea [174,52,195,219]
rightPlayerPortraitBrush "RaceSelectDialogTechRebelPortrait"

and it works the portrait alone changes to Psi and Tech but I need to seperate the Races. I.e. Have Human on left and Turian on the right.

Is there a location that defines the RaceSelectDialogPsiLoyalistPortrait DDS/TG File?

Any help appreciated.
