Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
Should images of dead people be used to raise awareness of humanitarian issues?
Firstly, the dead person should not be displayed in a way that is degrading, since the sanctity of the believer is the same whether he is dead or alive. Secondly there must be some benefit in displaying these images. Thirdly the person displaying them must have a good intention.
