What is the ruling on placing pictures of real people, such as a sad man or a crying child, in designs that speak of separation, and what is the ruling on placing pictures of children in signatures?

Photographing living beings, whether humans or animals, is forbidden. The prohibition is stronger if the picture is of a woman or a child and is intended for suspicion and lust. One must avoid situations of doubt and advise those who seek discord through such pictures. Nothing is exempted from the prohibition of photography except what is necessitated by need or dire necessity. There is no need to place pictures of children or others in signatures or designs, as natural pictures or drawings devoid of living beings can suffice.
