Want to use free images?
Two ways to use free images are through the public domain and Creative Commons licenses.
But what exactly do these terms mean, and what should you pay attention to?
Public domain
These are images whose copyrights have expired or have been waived, meaning they are freely available for anyone to use without permission or compensation. Public domain images can be copied, modified, and shared without restrictions even for commercial purposes.
Some institutions, such as libraries, museums, and other organizations, make parts of their collections available in the public domain. They often digitize artworks, allowing you to download high-quality images directly from their websites.
Creative Commons
The main difference between public domain images and images with a Creative Commons license is that public domain images are completely free to use, while Creative Commons–licensed images may only be used under certain conditions. Public domain images require no permission or attribution, whereas Creative Commons licenses often do require attribution.
