Showing Wife on Social Media

My sister-in-law is a female photographer, She wants to take a photoshoot of my wife and post it publicly on Social Media. My wife will be wearing a face mask and dressing will be modest, she does not wear hijab or niqaab but she dress modestly and no part of body except hairs are revealed.

I am not in favour of posting these pics on Social media and I am feared that I will become a Dayooth. That's why, I am asking my wife to refuse sister-in-law for posting pictures on Social media  for marketing purpose. But my wife said, it's alright as she will not be revealing body parts. Therefore, she is not agreeing with me.

Kindly, some Ullema brother or sister shed their guidance on this matter and tell me how I can solve this conflict.
