I built a test project that did this without using plug-ins.
The first step is to flip horizontal any busts you want on the right side (save separate images if you want both sides).
Then call pictures in events before the message is displayed.
An added feature is to do greyed out busts if you want...two ways to do this. Either create a general semi transparent silhouette to over lay or create duplicate images with a greyed-out overlay in layers.
Around 5am and can't sleep...It happens! Been a productive night at least!
Got my portraits working with a plugin, rather then "Show Picture" since that was too long of a process and I'm sure would have ended up with massive lag
