in the US at least, artistic nudity is protected speech under the first amendment, and the images would need to fail the criteria found in United States v. Dost to not be protected

the test is generally kind of shitty and there are a lot of images that historically would not have fallen afoul of obscenity charges that might fail the test

as a side note, it really is some shit - obscenity shouldn't exist as a concept (a CP ruling is independent of an obscenity one too, so you can remove the concept without stopping the law's ability to prosecute CP) and the Dost criteria are basically just the judicial system acting legislatively
