Non-free content policy
For purposes of this policy "non-free content" means all copyrighted images and other media files that lack a free content license. Such material may be used on the English Wikipedia only where all 10 of the following criteria are met.


 * 1) No free equivalent. Non-free content is used only where no free equivalent is available, or could be created, that would serve the same encyclopedic purpose. Where possible, non-free content is transformed into free material instead of using a fair-use defense, or replaced with a freer alternative if one of acceptable quality is available; "acceptable quality" means a quality sufficient to serve the encyclopedic purpose. (As a quick test, ask yourself: "Can this image be replaced by a different one that has the same effect, or adequately conveyed by text without using a picture at all?" If the answer is yes, the image probably does not meet this criterion.)
 * 2) Respect for commercial opportunities. Non-free content is not used in a manner that is likely to replace the original market role of the original copyrighted media.
 * 3) (a) Minimal usage. As few non-free content uses as possible are included in each article and in Wikipedia as a whole. Multiple items are not used if one will suffice; one is used only if necessary. (b) Minimal extent of use. An entire work is not used if a portion will suffice.  Low- rather than high-resolution/fidelity/sample length is used (especially where the original could be used for piracy).  This rule also applies to the copy in the Image: namespace. If your image is greater than 500&mdash;600px add  to the Image: namespace and someone from Wikipedia will shrink the image to comply with this guideline.
 * 4)  Previous publication. Non-free content must have been published outside Wikipedia.
 * 5)  Content. Non-free content meets general Wikipedia content requirements and is encyclopedic.
 * 6)  Media-specific policy. The material meets Wikipedia's media-specific policy. For example, images must meet Image use policy.
 * 7)  One-article minimum. Non-free content is used in at least one article.
 * 8)  Significance. Non-free content is used only if its presence would significantly increase readers' understanding of the topic, and its omission would be detrimental to that understanding.
 * 9)  Restrictions on location. Non-free content is allowed only in articles (not disambiguation pages), and only in article namespace, subject to exemptions. (To prevent an image category from displaying thumbnails, add __NOGALLERY__ to it; images are linked, not inlined, from talk pages when they are a topic of discussion.)
 * 10)  Image description page. The image or media description page contains the following:
 * 11) * (a) Attribution of the source of the material and, if different from the source, of the copyright holder. See: Citing sources.
 * 12) * (b) A copyright tag that indicates which Wikipedia policy provision is claimed to permit the use. For a list of image copyright tags, see Image copyright tags/Non-free content.
 * 13) * (c) The name of each article (a link to the articles is recommended as well) in which fair use is claimed for the item, and a separate fair-use rationale for each use of the item, as explained at Non-free use rationale guideline. The rationale is presented in clear, plain language, and is relevant to each use.

Fair use rationale
It is believed that the image...
 * ...has no free equivalent that is available, or could be created, that would serve the same encyclopedic purpose.
 * ...is not used in a manner that is likely to replace the original market role of the original copyrighted media.
 * ...adheres to Wikipedia's polices regarding minimal usage and minimal extent of use, and is of low resolution.
 * ...was published outside Wikipedia.
 * ...meets general Wikipedia content requirements and is encyclopedic.
 * ...meets Wikipedia's media-specific policy.
 * ...is used in at least one article.
 * ...significantly increases readers' understanding of the topic, and its omission would be detrimental to that understanding.
