stringer

In journalism, a stringer is a freelancer who contributes writing, photos, or videos to a photo agency, news agency, or other news organization. They are paid for each piece rather than a fixed salary. Stringers include journalists, photographers, or videographers. As freelancers, stringers do not receive a regular salary, and the amount and type of work is typically at their discretion. However, stringers often have an ongoing relationship with one or more news organizations, to which they provide content on particular topics or locations when the opportunities arise.
