Chessprogramming:Upload policy

This is a general outline of the upload policy of the Chessprogramming wiki.

Copyright and licensing

Before you upload a file, make sure that the file falls in one of the four categories:

• Own work: You own all rights to the file, usually meaning that you created it entirely yourself. In case of a photograph or screenshot, you must also own the copyright for all copyright-protected items (e.g. statue or app) that appear in it.
• Freely licensed: You can prove that the copyright holder has released the image under an acceptable free license. When in doubt, do not upload copyrighted images.
• Public domain: You can prove that the image is in the public domain, i.e. free of all copyrights.
• Fair use: You believe that the image meets the conditions for non-free content, which exceptionally allow the use of unlicensed material, and you can provide an explicit non-free use rationale explaining why and how you intend to use it.

Upload directions

When uploading an image, make the appropriate licensing choice in the pull-down menu.

Chessprogramming wiki encourages users to upload their own images. All user-created images should be licensed under a free license, such as the GFDL and/or an acceptable Creative Commons license, or released into the public domain, which removes copyright and licensing restrictions. When licensing an image, it is common practice to multi-license under both GFDL and a Creative Commons license.

Images can include photographs which you yourself took. The legal rights for images generally lie with the photographer, not the subject. Simply re-tracing a copyrighted image or diagram does not necessarily create a new copyright—copyright is generated only by instances of "creativity", and not by the amount of labor which went into the creation of the work. Photographs of three-dimensional objects almost always generate a new copyright, though others may continue to hold copyright in items depicted in such photographs. Photographs of two-dimensional objects such as paintings in a museum often do not. If you have questions in respect to this, please check the copyrights situation or ask for assitance.

Some images may contain trademarked logos incidentally (or purposely if the image is either freely licensed, covered under freedom of panorama, or being too simple to be copyrightable). If this is the case, please mark it as a trademark.
