Can I post photos of other people — including my kids’ class?

A photo where someone is recognisable is personal data; posting it publicly is processing. The household exemption covers genuinely private sharing — the family group chat, a closed album for the people who were there. It stops at public or semi-public posting: open Instagram accounts, large WhatsApp school groups, the sports club’s public Facebook page. There, the poster needs a basis — in practice, consent of the person shown. Children are the sharp end: class photos, birthday-party shots and team pictures involve other people’s kids — schools and clubs across Europe now run explicit per-child photo permissions, and parents can refuse and revoke. Post someone else’s child publicly without asking and you are on the wrong side of both the GDPR and, in many countries, portrait/personality rights that give the pictured person a veto — several countries also protect a person’s image through copyright-law “portrait right” provisions or case law. “Sharenting” disputes between divorced parents have reached courts repeatedly — judges increasingly side with the objecting parent and order removal. Adults in your shot: crowd photos where nobody is the focus are generally fine; a portrait-style shot of an identifiable stranger, published, is not — blur or ask. If it’s you in the photo: ask the poster to remove (screenshot first), use the platform’s privacy-violation report (all major platforms have image-removal flows), and escalate with Art. 17 — full route in the removal guide.
