Ooops! was working on some other things and didn't see this thread till now. The exact trigger point is 630-pixels on the width. Came to that number because if you run a top-spot banner in your sig that can be 624-pixels. So it gives a little margin of error between the two. Couldn't do it under 624 because that would kill any ref-code links on the sig banners.
It would have been a nicer fix if some people would have learned to resize images instead of just posting them right off their 5+ Mega-pixel camera's.
Never can please everybody.
