Actually, I was lying in bed, about to sleep, thinking about this last night, and it occurred to me that instead of a "frontispiece", I could have a "backispiece" -- so to speak -- that is, instead of putting the pic on the first page of the book, with the title page on the second, just simply flip them around. Then, I'd still have the title page with its accompanying picture together on the same two-page spread (when viewed in two-page mode) if/when the first page of the book starts on the left-hand page, and if it starts on the right, well, you'd have the title page, and then turn the page and still get a nice pic.
