A 30-year-old man pleaded guilty at Bradford Crown Court to possession of child pornography.
Simon Wilkinson, of Hill Street, Wibsey, Bradford, will be sentenced on May 20 after the preparation of a report by the probation service.
He admitted two offences of possession of indecent images of children, on or before September 28, 2011, and one count of possession of three extreme pornographic images, at the same time.
The court was told yesterday that the case was due to be tried on Monday but the hearing was vacated when Wilkinson indicated that he would plead guilty to the three charges.
His solicitor advocate, Andrew Walker, said he had no previous convictions and had been on unconditional bail.
Judge David Hatton QC adjourned the case until May 20.
He told Wilkinson: “You must not assume from the fact that I am releasing you on bail or ordering a pre-sentence report that that is an indication of the sentence that might be imposed.”
Wilkinson was ordered to sign on with the police as a sex offender with immediate effect.
