Roger Wirtz, of Sidney Road, pleaded guilty to three charges of possessing indecent images of children when he appeared at Northampton Crown Court on Friday.
Wirtz admitted possessing 35 of the most serious category A photographs, 12 category B images and 57 category C.
The photographs were uncovered after officers seized his computer hard drive after a search of his address on July 25, 2014.
Claire Howell, mitigating, said her client was “deeply ashamed” of his actions.
His Honour Judge Rupert Mayo said the court took these types of offences extremely seriously as the children in the photographs and videos had been subjected to harm and sexual abuse.
Wirtz was given a three-year community order and must complete the sexual offender’s treatment programme. Wirtz will have to sign the sex offender’s register and will have to notify police about any change of address in the next five years.
