I contribute a bit and as far as I know the only editor that lets you upload pictures is MapComplete, but even then what you can upload them for is very limited. I do not believe OSM actually has an image database. The pictures I’ve uploaded are all stored on Imgur.
This show was on every day after school on my local PBS channel. I watched it well into high school because I loved it so much. I love how it introduced you to a ton of different stories you may never have heard of otherwise.
