Letting someone post your baby picture

Adr
So I was wandering if any of you have any tips on how to prevent someone from posting publicly your baby pictures. I want to post my baby picture online whenever i decide it is the right time but how do i stop my entire family from posting them. I have a really huge family and most of them live abroad, i will be sending baby picture to some/most of them and i know they will go viral withing minutes, i just know i wont be able to control it at some point and someone will be posting them somewhere... Its hard to get in touch with everyone and ask to keep it private, when i say huge family i mean HUGE, and i dont want to sound mean to anyone by saying: make sure you dont post it blah blah... I feel like i will be out
of control... 👎🏻 Not sure how to handle this, any ideas? Thanks!!! ❤️🌷
