The standard Banner module is way too limited to be practical. Placed in the newsletter it makes for an extremely untidy display, even after going to the trouble of resizing all images to same dimensions.
Other 3rd party banner display modules I have at hand will not work. Images don't display.
At the moment I'm creating a complimentary article duplicating banners, and then placing that in the newsletter. Eseentially, a lot of tedious duplication.
Anyway, no matter. it was just a thought....
