[nextgen-gallery] firefox/chrome spacing problems

Ive inserted a gallery into a test page on my webpage. When I view the page in Internet Explorer, it works fine. When I use Chrome or Firefox, it leaves a page long blank space, and the gallery is way down at the bottom. According to the source code, there’s nothing between the text on the page and the code for the gallery.

What is causing this, and is there anything i can do to make it work in Firefox and Chrome?

Here’s a link to my test page with the gallery on it:
