I wanted to add "Tooltips" to the commenting functions below, as well as the permalink. This way, when you hover the mouse over the button, you know what it will do. Firefox expects the "title" tag to be used in the img statement, where as Internet Explorer pops them up with the "alt" tag. According to various sites, the "title" method is the way to do it. I just did it both ways, and it seems to work ok.
