Not wanting to spoil the fun, but
Content of a sexual nature will not be tolerated. No images containing bare female breasts, male or female genitalia, or explicit sexual acts will be tolerated. If the images are photographs that a reasonable person could discern as a human being these will be considered pornography and the User will be banned. If the images are not photographic in nature they will be treated as inappropriate content. No discussion describing explicit sexual acts will be tolerated.
Since the images had received complains about it, they have to go.
