A more thorough explanation:

Child pornography (CP) refers to any visual depiction, including photographs, films, videos, pictures, or computer-generated images, that show a minor engaged in sexually explicit conduct. This means that any sexual depiction of a minor is considered child pornography, even if the minor is not engaged in sexual activity.

For example, a picture of a naked child may be considered child pornography if it is sexually suggestive. This means that even if the child is not engaging in sexual activity, the picture can still be considered child pornography if it is intended to arouse sexual desire.

It is important to note that child pornography is not protected by the First Amendment and is illegal under federal law. It is a crime to knowingly receive, transport, ship, distribute, sell, or possess any child pornography. It is also illegal to persuade, induce, entice, or coerce a minor to engage in sexually explicit conduct for the purpose of producing child pornography.

Offenders of federal child pornography laws face severe sentences, including fines and a statutory minimum of 15 to 30 years maximum in prison for first-time offenders convicted under 18 U.S.C. § 2251.
