Indexhibit Support

Hi, i want to use a custom cursor and i have found the code but i don't know where exactly to paste it.

here is the code: snazzyspace.com/tumblr/…

Any tips?
Thanks a million!

Managed to figure it out and paste it after in index.php. but the problem is that it works just for the exhibit are and it switches to default over the index.

What else should i modify?
Sorry for my lack of coding knowledge.
Many thanks!
