I've been using Marinelli on http://watervilletroop108.org for several years with great success. However, I just noticed that banner images are not rotating well. When moving around the site, only a couple different banner images are used. Other users report seeing the same thing. Different people or different browsers/sessions might see different pairs of banners, but the code is clearly not rotating through all available banners. This does not appear to be a browser cache issue.
