I'm very new to C# and I've run into a problem and haven't been able to solve it. I have a row of buttons that have .png images assigned to them.

First off, I would like to say that myspace is a pain. But, musicians love it, and I can make some money doing layouts for them. I overlayed a layer of .png's over myspace's original look, but need to utilize the myspace music player.
