First Amendment rights are way too important to throw away over such a trivial issue. Images of nude people or people engaged in sexual acts aren't that big of a deal. If pictures are shared online in a way which invades a person's privacy or damages their reputation, then there are already laws to deal with that sort of thing. No new laws are needed to deal with this over-hyped minor nuisance.
The law contains no exception for "newsworthy disclosures" and requires "explicit permission" for any posting of images, etc. of a "person in a state of nudity or engaged in specific sexual activities." While this law would have made revenge porn illegal, it also made plenty of protected speech a criminal act.
