In this section, you can find several photo and picture websites where you can easily download the files.
Creative Commons
According to us the starting point for finding and using images is the nonprofit organization Creative Commons “dedicated to building a globally-accessible public commons of knowledge and culture”.
NOTE
The term creative commons is also associated with a relatively new type of copyright license. The idea behind Creative Commons is to allow artists to share their works with the online community without a price but with certain conditions so that the original creator gets credit. Creative Commons assets are still protected under copyright laws unless they’ve been placed in the public domain, but the terms of the license are clearly and uniformly defined.
FLICKR
Flickr is the world’s largest online photo management and sharing resource, created by Ludicorp, a canadian company, in 2004 and acquired by Yahoo in 2005.
The number of photos shared on flickr under a Creative Commons license is about 500 million (Last updated 3/8/19)
WIKIMEDIA
The nonprofit Wikimedia Foundation provides the essential infrastructure for free knowledge. Wikimedia hosts Wikipedia, the free online encyclopedia, created, edited, and verified by volunteers around the world, as well as many other vital community projects.
Wikimedia commons is a media file repository making available public domain and freely-licensed educational media content (images, sound and video clips) to everyone, in their own language.
The homepage proposes also monthly challenges
Here you can find billions of images organized in collections including also the “Museum collections”, “Flickr” and “Wikimedia commons”.
