Is it permissible to publish pictures of slain Muslims with their limbs dismembered and their blood flowing, and does the ruling differ regarding pictures of the corpses of non-Muslims?

Scholars have differed regarding the ruling on images captured by machines (cameras), and the more preponderant opinion is that they are permissible as long as they do not include anything unlawful. This permissibility is further emphasized when there is a benefit, such as the situation mentioned in the question, due to its role in raising awareness among Muslims about their duty towards their brethren.
