Alternatively you could make the entire banner a sliced image and squeeze the whole thing together in a table with the different sections pointing to wherever you like.
Personally, I block most graphical adverts. They are removed from the page and/or not even downloaded. By and large, I don't bother to do the same with text-based adverts.
Without getting into the rights (and wrongs) of the publisher and the client, you should know that I'm not alone. You could take the view that it's no loss, since I'm hardly likely to buy anything through adverts I'm actively stripping out, but if you rely on advertising income it might be something you want to bear in mind.
