Blank Sidebox as Linked Graphic Only

[charagg]

I was wondering if you could help me figure this one out. I've gone one Logo Sidebox that I don't want to show up on the home page, as well as, several other ezpages. The code to hide on the ezpages is fine and listed below, I'm just not sure how to hide on the home page too. Any help would be greatly appreciated! Thanks!

Code:
