Yeah, you want to be using the GtkDrawingAreaWithAJPEGAsABackground 
widget...

Just load the JPEG into a pixbuf (gdk_pixbuf_new_from_file), and render 
the pixbuf into the drawing area before the user starts to scribble 
(gdk_draw_pixbuf(widget->window, NULL, my_pixbuf...)). How much more 
obvious could it be?
