Ian Lomax, 30, was jailed for 16 months after a court heard the vile images were discovered after police executed a search warrant at his home in Ackworth, near Pontefract.
Leeds Crown Court heard West Yorkshire Police officers received information that abusive images were being accessed from through an internet service provider address in his mother’s name.
Gillian Batts, prosecuting, said a total on 904 movies and 117 images featured the sexual abuse of children. Officers also discovered over 2,00 images and movies featuring the abuse of animals. The computer equipment also contained file sharing apps.
Lomax had carried out the offending from June 2012 until the equipment was seized in May of last year. Lomax, of Mount Pleasant, Ackworth, pleaded guilty to three offences of making indecent images of a child and one of possession of extreme pornographic images.
Rukhshanda Hussain, mitigating, said: “He has felt nothing but guilty, even when committing the offences. He wants help for something which has become an addiction of the years.”
Judge Jacqueline Davis told Lomax that she was unable to suspend the prison sentence because the offending was so serious. She said: “The age of the girls and the period over which you were participating in this kind of activity, together with the file sharing apps, make this sort of case one where there has to be an immediate sentence of custody.”
