Former Jersey Police officer Peter Whitehouse will serve three years behind bars, after pleading guilty to seven counts of possession of indecent images of children.
Whitehouse, 56, was arrested and charged in April with downloading the most severe level of indecent child abuse images.
He pleaded guilty at Jersey's Magistrates Court in August and was jailed for three years at the Royal Court today.
He was also placed on the Sex Offenders Register for five years.
In summing up, the Bailiff William Bailhache said his conduct "has brought shame on the Police Force and the charity he worked for".
Whitehouse was employed by Prison Me No Way as an educator, an organisation that aims to raise the awareness of young people in the Island about the causes, consequences and penalties of crime.
The States of Jersey Police says it conducted a thorough investigation and found no evidence of contact offending.
The weekend event coincides with International Pride Month and the 51st anniversary of the Stonewall riots.
The scheme has been backed by the island's Lieutenant-Governor, and is the first of its kind in the Channel Islands.
