Speeding up image uploads?!

Does anyone know how to speed up image uploads? I uploaded new poster images for a second season of one of our shows over a week ago (from the main production companies IMdB Pro account) and they are still not showing, nor are many of the episodic images I've tried to add. It's really important that the main artwork on the show is updated, as the cast are completely different from series 1. Is there a way of getting this through faster?!
