It seems like it would depend on how olfactory-centric the culture is, to me. Our culture seems more visual-centric. Probably because the smog and various related crap we dump in our air causes our noses to generally suck. But if someone was much more attuned to scent, I could see a scent being a very erotic "image" (after all, if you believe popular TV commercials, scent is the longest remembered of the senses . . . of course, I don't particularly buy that one).
There is also the option that both meanings are intended. After all, the greatest poet of all time playing on the fact that the word is both visual and olfactory doesn't seem like such a stretch . . .
