📸 Photo guidelines
Every task at every difficulty is verified — 2 photos · AI + leader check.
- • Photograph the action, not the person — the bag, the bike, the bottle, the seedling.
- • No faces, names, school crests or house numbers in the frame.
- • Only upload photos you took yourself.
PlantMax's reviewer only looks at what the photo is of — litter, bikes, bottles, plants. It never identifies or analyses people, and it never rejects on its own: unclear photos go to your teacher.
