[plugin NextGen gallery] Thumb not displaying properly in post

For whatever reason (which I’d like to resolve), any time I put a gallery link in my post it appears waaaaay down at the bottom of the post with a huge wall of blank space above it. You can see it at my website now at ninjadoll.net. I’d like to get the thumbnails to appear with a reasonable space buffer but not a whole page worth =P

I’ve checked my theme’s code and don’t see a reason that they would make this happen.

Help?
