- Take the “before” photo and the “after” photo from exactly the same spot, at the same height (mark where the stand goes on the floor).
- Use the “after” photo as the space’s photo (“Photos” step).
- With “Toutes les options” (all options), “Photos” step, on that space, tap “Ajouter une photo « avant »” (add a before photo) and choose the photo from before the work.
- Publish or update the tour. In the space, the “Avant / Après” button (before / after) appears: the visitor drags the slider, and both photos turn together.
- Do the same for each transformed space. “Retirer l’avant” (remove the before) removes the before photo; nothing else changes.
Same height, same spot, same light: the visitor immediately sees what has changed.
