The "uploaded by photographer" licence is if you had taken the image yourself, or in this case you created it.

The image at https://en.wikipedia.org/wiki/File:Operant_conditioning_diagram.png has the licence code of GNU Free Documentation License. The equivalent is This file is licensed under a free license.

However, I think is more appropriate licence is: This file was originally uploaded on Wikipedia or another Wikimedia project. as it has come from Wikipedia
