I like Unsplash as I selected Nature and then the picture that I liked. I use pictures as a way of engaging students in art and nature through visual representation. Unsplash is an open-source, therefore, anyone can post their pictures. When the picture is shared or downloaded, the authored is acknowledged and all information is available to viewers. https://unsplash.com/@_davidgavi Each picture has details and information available. An easy to use website that has over 1 million free high-resolution pictures.
