Beyond simply sending such material to one person or another, distribution includes peer-to-peer networks, privately printing images, saving the material to a disc or thumb drive, or storing the material in a separate area on a computer hard drive. Defense for this charge entails proving that the accused knew what was being distributed, and plausibly explaining why the material was stored where it was found. Punishment for being found guilty of distributing child pornography can include imprisonment from five to twenty years and being required to register as a sex offender.
