Images posted openly on the web are still protected by copyright and are not automatically free to use. To find images, you should look for images labeled "public domain", or have open licences that allow them to be shared freely.
Public Domain means the image is not protected by any copyright law or other restriction and may be copied, shared, altered, and used by anyone. The content is typically in the public domain because either the copyright expired or the content owner intentionally placed it in the public domain.
Open Licence means that the creator has assigned a licence other than copyright (most often Creative Commons) that grants you permission and states restrictions on what you can do with a work.
Sites with Free Photos (some with restrictions)
These sites offer free images with licenses for noncommercial, education use. Check each site's license or rules page for their regulations.
Search for Images licensed for re-use under Creative Commons.
Creative Commons is a open licensing system that allows content owners to clearly indicate how you can use their image. Creative Commons licenses have attributes that state if an image can be used for noncommercial purposes, can be modified, and more.
Use https://search.creativecommons.org/ to search multiple sites for images that can be shared and modified.
REMEMBER: Even if an image is licensed for reuse, you still need to cite your source!
