Pornography
In the law of most countries, showing naked people is not called "pornography" unless the people are doing something sexual; even so, material that counts as pornographic may still be legal. When people consider photographs or movies to harm or to disrespect the people depicted or the viewers, or to violate the community's moral or religious standards, they condemn the material as "obscene."  Most countries have laws against obscenity. One type of pornography against the law in most countries is child pornography.
