Where do i change the thread icons?

[kobescoresagain]

Okay I made a few different "Forum Contains New Posts" and "Forum Contains No New Posts" icons that I would like to display. Where does it decide which one to display? What I sould like to do is to change them to the symbol for the sport that they relate to. So I can't just change the image itself.

Second, please correct me if I am wrong or if you know exactly the cod efor it please post. But all that would really need to be done is to do an if else statement where if teh forum is x then it displays x. Right? Or would their need to be more done?
