Bad location of next page bar

If you have more than 1 page of photos in the gallery the 1 2 next bar is overlayed on the photos above it. See http://www.darlingtonschoolhouse.org/image/tid/4 for an example (may be gone by the time someone reads this as I am working on the problem).

I suspect that it may be because I modified the thumbnail image sizes to only specify the width and left the height open. Yup that was it, just specified the height and the problem goes away. So now you know where the bug is. Sounds like you need to set the height to the largest of the thumbnails.
