How do you change the new post/no new post icons?

[kobescoresagain]

I know you can do it by changing the image, I want to do something else though. I think I can figure it out if someone can just tell me where you can find where in the templates it is posted. i believe it is in the "forumhome_forumbit_level1_nopost" and the equivalent
forumhome_forumbit_level1_post" But can't seem to figure out where.

Thanks
