A WAGGA principal says protecting children's privacy is difficult in the age of social media and parents are putting it in jeopardy.
Wagga Christian College principal Phillip Wilson said parents who do not want their children to appear in photographs or videos could use the opt-in, opt-out system that is used by most schools.
However, he said the city's parents need to know that nowadays this system is no longer foolproof.
"It is important for parents who opt-out to know their child could be photographed at some point, which is out of our control," he said.
"That is something we have to put up with, unless we want to isolate the child from the world."
Mr Wilson said the problem was parents taking photos of their children at school events, which are then shared on social media.
He stressed that it only takes one wrong person to see the photo and it could put a child in danger.
"While we cannot take the student's photo, they can get their photo taken by anyone else," he said.
"Our information nights show parents how social media looks like for kids - when it goes well, it goes really well, but when it turns a bit poorly it's out of control.
"A parent might only be taking a photo of their kid and friends, but an estranged parent might see that and suddenly they know where their child is."

A Wagga mother, who wished to stay anonymous, said protecting a child's privacy was no easy feat in the age of social media.
Her 10-year-old son has strict rules surrounding social media because the dangers of the internet was a pressing concern.
"My ex-husband and I have very different views about social media. My son doesn't have social media in my house, but he has Instagram at his father's," she said.
"When it comes to any technology, he always uses it in a space that we can walk past - never in his room."
While she has no qualms about her son appearing in videos and photographs on social media, she respects that other parents' views could differ from her own.
"I know the implications about a photo being released of a child in the foster system," she said.

"The child might only appear in the background of a photo taken at an athletics carnival - it causes so much risk for the child.
"It can be challenging to monitor and there is no easy solution to the problem.
"A person grabs a photo of the winner crossing the finishing line at a race and the foster child who comes second appears in it too - it just happens."
Despite the challenges, she said parents need to work with the school to ensure their child's safety rather than blame them.
"A child's safety is their responsibility and parents need to understand the dangers and risks," she said.
