Since Pixabay was launched in November 2010 a growing community (over 100,000 peopel from allover the world) has turned this project into the greatest, high-quality source for free images and videos. 

With a total of 1.5 million free images, most of them photos (1.2 million) and several hundred thousands of illustrations, vector graphics and clip arts, Pixabay is the largest collection of free quality images.

You can search public domain images by using keywords or by browsing through the libraries. You can download them in different sizes.

Pixabay is one of the best choices to find free quality images for classroom projects avoiding copyright violations.
