Thanks; I don't have the actual book, but had looked at the online examples and not seen anything. Now I go back and see he does have one example in chapter 3 (using a photo of the moon) and I just hadn't noticed it. I think I got frustrated because I was typically searching for "image", and R uses the term "image" for something different. I was also imagining it would be some kind of "background" parameter, and it wasn't. :-( Anyway, thanks again: I now have what I need. Robt
