@martin Pictures isn't a part of OSM. You can refer to a wikipedia article (which embedds photos), or make streetphoto sequences using #mapillary. But this isn't dedicated to the internal interior. Both can be embedded. You might want to use https://osmybiz.osm.ch to add the business?
OSM focus on objective information which are collected on the ground and could be verified by everybody else. Not internal kowledge or adds.
