Openverse

Discover over 800 million creative works. Warning: Openverse classifies, indexes, and manages the library of stock photos, images, and audio but does not own them. Each author or owner can set their terms and conditions for use. This means that when using an image, you should carefully check the terms of use. Often there are no conditions at all. Other times, attribution is required, or it is only permitted if it is non-commercial.
