Sean,
I'm not entirely sure, but I think I saw my image, once or twice when I ran
it the other way (with the ImagePortrayal3D).  But it looked like the width
was set to 1.  That, along with the error message below leads me to believe
the image width is not set correctly.  I'm not sure how to fix that.

I put in the code to do the setBackdrop.  The error message is below:

Ryan, this last statement is the one of particular concern to me.   
I've just tested again and have no problems with setBackdrop.  Can  
you provide the full backtrace that came with this exception?
