No, you do not appear to have any legal recourse: 1) Harassment is harassment of you--not sending other people information about you.2) Slander is the making of untrue factual statements to others which damage your reputation--but if these are actually your mugshots, then it's not untrue, and truth statements (or pictures, etrc.) are not slander.3) There is no law preventing employee A from trying to prevent employee B from getting or promotion, or even trying to get employee B fired.
