Parents are being warned to think carefully about what they share when posting their children's first-day-of-school photos online.

A San Juan mother says those special moments can reveal more information about a child than parents realize.

"The less information that you put out there, the better it would be because you never know who's watching," San Juan resident Kayla Lozano said.

Lozano's three children attend Vanguard Academy. She says taking a first-day photo is a tradition, but she checks what's in the frame before posting.

"I try [to take photos] away from street signs. I make sure that there are no street signs [visible]," Lozano said.

She also limits who can see the photos and avoids sharing the school's name, the teacher's name, or other personal details.

"All I'll share is probably just what grades they're going to," Lozano said.

Cybersecurity experts say parents can take simple steps to limit the information shared in photos, including checking privacy and location settings.

"Depending on the application you're using. For example, geolocation on Facebook, you can go on there and turn that off if you're ever going to post a picture of your child. That way, they don't know the actual location," Cybersecurity Instructor Fernando Mercado of South Texas College said.

Mercado also warned parents about how photos of their children could be used with artificial intelligence.

"With AI nowadays, you know, there are profiles of people that make it seem like they're a real child. They're real, and they can easily befriend your child, and you not even know," Mercado said.

School districts are also educating parents on best practices to protect their children.

"It's important that parents know about privacy features within these platforms," Leon Middle School Librarian Celeste Lopez said. "They need to set those parameters themselves because, yes, if an account is not set to private, they are sharing and disseminating all of this information for the entire world to see." 

Lopez said McAllen ISD holds workshops throughout the year to help students and parents learn more about cyber safety.

"Sometimes, although well-intentioned, they post pictures. They may share grade levels, full names, schools, school logos, addresses. And so these are things that we need to be cognizant of and very careful when sharing our photos," Lopez said.

Lozano says everyone needs to think twice before they post.

"You never know who can be watching or who is lurking," Lozano said. "Not everybody is bad, and we don't want to think that there are bad people out there, but it does happen, unfortunately."
