I’ve been contributing to Google Maps for a while, specifically, I usually upload pictures of menu’s from restaurants, so future visitors can see them before they decide to eat there! I’m trying to degoogle my life a bit & was wondering if there is a way I could contribute these to OSM?
For photos, Wikimedia Commons seems like the best approach, although really any website will do (as long as there are no licensing issues w/ that site and OSM). There is a whole wiki page about linking OSM features to photos.
Unsure about reviews, though.
