The picture is irreverent, but the objections to it are blasphemy. They deny Allah's transcendence and paint him a a humorless crybaby easily reduced to wrath. The existence of Allah is a matter of faith, His sense of humor is not - one look at a platypus, or in the mirror, proves it by direct observation.
Either laugh and move on, or meditate and repent your arrogant judgment of others. You never know when you might live.
