The U.S. Attorney's office says 46-year-old Gary Jay Hibler will not be eligible for parole under the sentence imposed Friday by District Judge Eric Melgren.
Hibler, from the Finney County town of Pierceville, had pleaded guilty to one count each of producing and possessing child porn.
Prosecutors say the investigation began when immigration agents learned that a couple from Australia had been trading child porn with a man in North Dakota.
Images on that man's computer were traced to an Internet account in Pierceville, and an adult male shown with a child in the pornographic material was identified as Hibler.
