One of the flaws with this banner idea. Wikia isn't going to get rid of the ad and I doubt they'll apply any size restraints to it just like their other ads that are never one size. Narrowing the image might be okay for some wikis; others likely not. At the very least, good for them for getting rid of the navigation.
