Steven Ray Hemenway, 47, was sentenced Tuesday in federal court in Boise, according to a press release from the U.S. Attorney's Office.
After the prison time, Hemenway will serve 20 years of supervised release and undergo "treatment for sexual deviancy," the release states. He will also be required to register as a sex offender and follow other conditions designed to protect the public.
Hemenway pleaded guilty in December to one charge of possessing sexually explicit images of minors.
The charges were prompted by an investigation that started in December 2012, when Canadian investigators searched a residence in Toronto. They found evidence that a man there had sent child pornography to an email account associated with Hemenway.
Federal agents and Payette police officers visited Hemenway's home in February 2013, and he admitted to them that he had sent and received child pornography over the Internet for several years. An analysis of images found on Hemenway's computer concluded that they featured known victims from seven U.S. states and five other countries.
