Piggy Petter

The blog has a great new feature that you can see just to the right. The piggy would be very happy if you would gently pet it with your mouse cursor. I'm looking to make a more fully featured piggy petter, but I'm having some technical problems. If you are or if you know someone who is good at changing images with white back backgrounds into images with transparent ones without weird jaggy halos, please let me know.
