Welcome! Yours is an interesting question, even if I believe the CSS specs say nothing about this, so browsers are free to do what they prefer. As far as I know (checked looking at server's logs and/or http traffic) all the current browsers (and probably also older ones) do not make requests for not used background images (i.e. mentioned in CSS rules whose selectors do not match any element on the page.) The only exception is IE5.2 on Mac (which is not a current browser.) (Don't take this as a definitive answer, things may depend on circumstances that I have overlooked.) Browsers behavior is more different in the case of background images attached to elements with display:none. In this case some (IE, Safari) seem to request the image anyway, others (Gecko, Opera) do not.
