This is the best place to post. Folks here are already sharing in this public (ie open to the public) forum. But if they do not want it shared beyond this place (perhaps due to a dislike of Facebook or whatever), they can state it in the post.
If the poster does not say who they are, the PR Social Media team will just share the pictures.
