title: Rollover Image has an unwanted grey bar under a .png image
body: <p>I created a rollover image in Photoshop. It was created in a square shape canvas .png. The image is a circle. I created one image normal and one image highlighted as the rollover. The rollover image has an unwanted grey line under it, I don't understand why it is there...</p>
