Griffith man Neil Cranston, the parent of a former student, demanded Griffith High School's former sportsmaster Murray Jones be erased from the photos on show in the school's foyer.

Mr Jones was sentenced to six months detention in a correctional facility in 2007 after setting up a hidden camera and filming a 17-year-old boy in his bathroom.

"We're trying to teach ethics and morals to our kids but it's impossible to do that successfully when our schools are setting this sort of example," Mr Cranston said.

"Why would the school want to be associated with someone like Mr Jones, no matter how long he worked there?

"Those photos are in pride of place; they're one of the first things you see when you go into the school.

"What he did is disgusting, he's a convicted criminal and I don't want him up there in pictures with my son."

Mr Cranston said he first asked the school to remove Mr Jones from the photos in October last year.

Mr Jones was dubbed the "bathroom spy" after his young victim, who was living in the teacher's house at the time, discovered a camera encased in cling wrap hidden in the dirt of a pot plant, pointed at the toilet.

Jones was instantly terminated from his position at Griffith High School in March 2007, when he pleaded guilty to installing a device and filming for an indecent purpose in Leeton Local Court.

School principal Charlie Cochrane, who was not at the school in 2007, said one photo of the former teacher had already been taken down and he was examining the options for removing other photos.

"We are taking them down but it's an interesting situation because we've only had one official complaint," Mr Cochrane said.

"I do understand where Mr Cranston is coming from and we will have to do something about it.

"We'll look at editing the pictures in Photoshop because we want to leave the students up there."

The photos will be out of sight for some time while Mr Cochrane completes the task but he has guaranteed they will return to prime position in the school foyer.

Murrumbidgee MP Adrian Piccoli who is also the state education minister supported the decision to cut Mr Jones out of the memorabilia.

"This is not the sort of thing that would be brought to the attention of the minister for education but Mr Cranston came to me as his local member," Mr Piccoli said.

"I understand what he is saying and the teacher in question did leave the school in unpleasant circumstances.

"It is not a good situation to have a reminder of that teacher prominently on display, so I am sympathetic to the cause and am pleased the principal has undertaken to remove his image from the photos."
