I'm still not convinced that with tvimage I could do what I want without
worrying about anything else. Anyway, it works now, and as it had been
mentioned before, one shouldn't try to optimize working code just for
the sake of it ... Next time I write an image display program I'll think
about it again.

Hmm, somehow I missed this even though I use programs from your library
