CCleaner Button help please

I am not thinking clearly today (?) I guess. I just wanted to put a CCleaner link on my blog, but I don't know how or what to change to make it work. Obviously, I need to put something in where [path to image] is, but what? Please help this sorry little doofus! LOL :P Thanks very much!
