Drupal Advertisement/Banner module

Hi there,

I am looking for a banner rotation module with the following features. Support of multiple standard-size banners, and consistency in their presentation. For example, if I have two different spots on the site - one for large and one for small banners, to show the banners according to their size, instead of merely scrambling them and picking one randomly, regardless of its size.

Moreover, I need a module that allows for multiple spots to be located on the site, instead of just one.

I tried the Advertising module, but it did not prove very good in terms of the features I want.

Can you help, please? I am not afraid to write code if it is necessary :))

Thanks
