what if the image was only partially on the button?
That's what I was going to do. I just didn't do it with the speakers because it doesn't look good withe the speakers half off or partially off; they would have to be separate if so.
In order to have transparency, you can only use gif algorithms. I have transparency on the buttons above for the corners.
I also rethought that clarion one; we can't use it because the Edit button only shows up for your own posts.
I also agree that the buttons should be larger. Think 1.5 times is too much? I'd change them now, but I'm not home right now.
