Seeking guidance as to my rights as an employee against parents of patients taking my picture (& their child) w/o my consent, posting on social media

Parents should be reminded that once a hospital photo is on line it violates their child's HIPAA rights. A potential employer might discriminate against that child down the road. Remind them that privacy is important for both you and the child. No one should be able to identify where you work unless you consent. Ask the parent if they would consent to having their picture taken with "psychiatric wing" printed above the child's head? Or of the actual intimate procedure being performed on the kid? Pictures are for outings. Going to the hospital does not qualify. Education is key. Unfortunately social media is out of control and many have no idea of the potential harm it creates. HR could make it a policy. But enforcing it would require in hospital security removing the parents. Kind of tough to forbid cell phones in hospitals or have security run around and tell parents no photos like they do at the Met. Not the Mets. If you used the former example their response might be "where is that"?
