What is the Quran and Sunnah rulings on posting pictures of the faces of the deceased?

Pictures of all animate objects are forbidden and haraam in Islam. Rasulullah (sallallahu alaihi wa sallam) has sounded severe warnings regarding it.

Nabi (sallallahu alaihi wa sallam) said, “The people to be inflicted with the worst punishment will be the picture makers.” Nabi (sallallahu alaihi wa sallam) has cursed the one who receives interest, the one who gives interest, the tattooist, the tattooed and the picture maker.

The Hadith also explains that the angels of mercy do not enter a home in which there is a picture of an animate object.

Furthermore, posting pictures of the deceased will be a cause of punishment for them (if they had consented that their pictures be taken). If you have any pictures of the deceased, then you should immediately delete the pictures and repent to Allah Ta'ala.

And Allah Ta'ala (الله تعالى) knows best.
