Convicted paedophile David Honeyball, 56, of Turpin Close, was found with images on his computer after a police search at his home on 24th May.
Andrew Scott, prosecuting, said most of the images were found in the computer’s recycling bin but a file sharing system was also present.
Mr Scott told the court chat logs showed Honeyball was ‘willing and able’ to share images but it was impossible to be sure if this had occurred.
On arrest, Honeyball said: “I’ve only been on it for about a month.”
He admitted being aware of the file sharing system but claimed he only looked at images once to pass them on to the sex offenders unit at Lincolnshire Police.
The court heard Honeyball was jailed for three years at Snaresbrook Crown Court in 2000 for an indecent assault on a young child, and had also received a four year prison sentence for historic sex offences.
He admitted five charges of making and possessing indecent images of children, and one of intending to distribute them.
Judge Micheal Heath remanded him into custody to be sentenced in September.
