Faint border around picturebullet image

I added some simple images to the PictureBullets collection but when I use them as bullets there is a faint white border around the bullet, which is evident when used over a non-white background. The images themselves do not show a border. Is there a way to turn off the border on the bullet image when it gets used?

Thanks,
