Openverse

openverse.org

Suchmaschine für hunderte Millionen frei lizenzierte Bilder und Audiodateien, mit Lizenzangaben für korrekte Namensnennung in deinen Projekten.

Openverse searches hundreds of millions of openly licensed images and audio files and surfaces the specific license each one carries, which matters when a notebook's output will be reused or published somewhere that needs proper attribution. It's a search layer over other repositories' content rather than a host, so double-check the license on the original source page before relying on Openverse's listed terms. It's built for finding reusable media, not for scholarly citation the way a bibliography source would be.
