	If you can transmit keyboard command (say, space for next page)

	Add some code into draw_one() to check additional file descriptor.

	I don't see what you exactly mean.  How do you plan to specify
	alternate source for image? (command line option, or the alternate
	file descriptor described in (1)?)
