Finding photos and images for teaching materials can be challenging because of copyright considerations. However, stock photo libraries that offer free photos under the Creative Commons Zero license (CC0) are becoming increasingly popular. A CC0 license means that the photographer has relinquished all copyright and other rights to his or her content. This means you can use the images free of charge even for commercial purposes without notifying the photographer.
One of the largest and most popular libraries is Pixabay that offers a collection of high-quality photos, graphics and videos. You can freely download, publish and edit content without asking permission from the original author.
