Convicted murderer Daniel Kelsall has been sentenced to six months in jail for possessing computer-generated child pornography images.
But it will make little difference to the former trainee chef who is already serving a minimum of 30 years for the stabbing murder of Sydney man Morgan Huxley.
Almost four months after he was sentenced over the killing, Kelsall pleaded guilty at Central Local Court to possessing more than 30 computer generated pornography images.
The Japanese anime style images were found by police while they were searching Kelsall's home as part of the investigations into Mr Huxley's death.
In sentencing him, Magistrate Alex Mijovich said he saw no benefit to the community in extending Kelsall's current sentence, which could see him imprisoned for up to 40 years.

The images were also on the lower end of the spectrum as they did not contain actual children, only computer-generated ones.
The sentencing comes after Justice Robert Allan Hulme described Kelsall's killing of Mr Huxley in September 2013 as the work of a "very disturbed mind".
The 22-year-old first spotted Mr Huxley at the Oaks Hotel in Neutral Bay and then followed him from the pub to his nearby unit.
When he realised the door was left open - as was Mr Huxley's habit - Kelsall went inside and attacked the 31-year-old as he lay either asleep or incapacitated by alcohol.
He indecently assaulted him before plunging a knife into him more than 20 times.
Describing it as a "chilling case of murder", Justice Hulme said at the time, "whether the offender killed for the thrill of it ... or whether it was as a result of fantasy or obsession I am unable to say. It was entirely senseless and needless".
Kelsall's parents, who had sat in the gallery during his murder trial, were not in court for his sentencing on Monday.
