As a high school coach, what are my rights if I am sexually harassed online by my athletes?

I am a high school coach and several of my athletes posted many obscene, Photoshopped images of me on their Facebook pages. These include sexual images with my face superimposed and also violent images, such as my face with a knife over it. They also made sexually harassing comments and photo tags. The school is involved, but since it is summer, the only recourse was a signed confession and a two-game suspension. What are my rights in this situation? These athletes are still on my team and I feel uncomfortable. I am also afraid that this may have cost me a teaching position at this school since it occurred shortly after my interview.
