[Plugin: NextGEN Gallery] Nextgen not working with 'Next' function

Hi,
I’ve put together a Nextgen Gallery – http://www.emidi.net/websites/holly/gallery
and when you click on an image is displays correctly however then when I want to scroll to the next image it does not work correctly.
If I exit the photo I can scroll, but the Nextgen border changes and looks messy.
If someone can help me it would be GREATLY appreciated!
Thanks 🙂
