Below are three websites I am adding to the list of the best platforms for public domaine pictures. You can use these resources to download and print pictures and images for free. Students can also use them to search for pictures to use in their multimedia projects.
1- Pixabay
On Pixabay you may find and share images free of copyrights. All pictures are published under Creative Commons public domain deed CC0.You can copy, modify, distribute and use the images, even for commercial purposes, all without asking permission and without paying attribution.

2- Pic4Learning
3- EveryStockPhoto

This is a search engine for free photos. These come from many sources and are license-specific. You can view a photo's license by clicking on the license icon, below and left of photos. Membership is free and allows you to rate, tag, collect and comment on photos.
