Xml thumbnail Problem

1

Hi, I just made a gallery just like http://www.kirupa.com/developer/mx2004/thumbnails.htm tutorial.
And it looks like this. http://vind.bafel.se
Now as you can see there is three different kind of galleries one for monster, one for dairy and one for characters.
When the page loads it is the monster gallery that you see. Now if you scroll far to the right and then you go to the for example character gallery you see that some of the thumbs from monster gallery remains.

How do you fix this?:look:

here is the code:
