A former Brighton assistant head teacher who admitted making and possessing indecent images of children has been jailed.
Kenneth Browne, 60, of Blackheath in south-east London, was sentenced to 10 months at Hove Crown Court.
He was also banned from working with children for life and was placed on the sex offenders register.
The former teacher at Dorothy Stringer High School was first arrested by Sussex Police detectives in July 2007.
Officers seized equipment at his former home in Havelock Road, Brighton, on 29 July 2009.
He was dismissed from the school soon afterwards and moved away from the area.
Officers said the charges were internet-related and the "making" offences related to moving images onto a memory stick.
The images related to girls aged between 10 and 13 and did not involve any children at the school, police said.
Detective Inspector Ali Eaton, of Sussex Police, said the sentence reflected the seriousness of the offences.
She said: "Although the majority of the images were not of the most extreme type, it must be understood that every such image represents child abuse."
Browne admitted six counts of possessing indecent images of children and six counts of making indecent images of children at Lewes Crown Court on 20 January.
