这是一个乍看起来可以用在维基共享资源中的劣质来源的列表，但仔细检查后都不能用或者自相矛盾。来自这些地方的文件都应该加注{{subst:nld}} （“缺少版权”）或{{subst:npd}} （“没有授权”）模版。这样做可以将这些文件放入适当的子分类Category:未知中。

劣质来源列表
- Alchetron将维基百科条目与大量网络上的非自由和经常被错误识别的图像相结合。在他们每个页面的底部确实有一个“CC BY-SA”的声明，但这个声明指的是从维基百科上摘取的文本部分，不适用于图像。点击网站上的图片，会以 “访问页面”的形式提供该图片的“来源”，当然，这里的“来源”只不过是原图的深层链接而已。
- 声称他们并没有版权的截图内容适用于{{Cc-by-sa-3.0-nl}}。
- FotW的版权政策中包含一些不可接受的限制：
- ...内容仅可用于非商业和非政治目的
- 如果你以非网络方式（例如：软盘或CD）传播我们的材料，你不能出售他们
- 你最多可以使用5%的图片或网页内容
- 你不能以任何方式改动图像或文本内容
- 请勿上传任何来自此站点的图片，除非您提供一个非常好的原因（示例）
- At first sight uploading on Commons seems to be OK: the sites mention "Free license", "Attribution is required", "allowed for use on commercial and personal projects, for an unlimited number of times and without any time limits, anywhere of the world". But that is misleading. It turns out that in the Terms of use the terms "commercial" and "use" are very narrowly defined, making this not OK for Commons. See the Village pump discussions Is pngrepo.com credible and Freepik images.
- The usage conditions [1] are restrictive:
- The images must not be provided for download (elsewhere) in the Internet. (original German: "Die Bilder dürfen nicht im Internet zum Download angeboten werden.")
- The images must not be included in (other) collections of images. (German: "Die Bilder dürfen nicht in Bildersammlungen einverleibt werden.")
- 这两条要求已经十分明确的显露出这个网站的照片不能在维基共享资源使用。
- While they claim to be licensing their images under the Creative Commons Attribution license, the page that links to it adds several more restrictions, namely,
- The use of these images for advertising, marketing, or any other commercial purposes is prohibited. These images can be cropped, but may not be altered in any other way, and each should bear the credit line "© GM Corp."
- Despite the text of the license they linked to from their licensing page, their intent is quite clearly to allow a non-commercial, no-derivatives attribution license, which is not acceptable on the Commons. Whether linking to the CC BY license would invalidate these stated restrictions is a finer legal point than we are qualified to deal with; furthermore, even if this would lean in our favor, it is also good form to respect the intent of copyright holders, rather than try to catch them out on legal technicalities like this.
- (On a related note, there are GM media pages such as this Chevrolet Austria video page which mentions "© Creative Commons Attribution 3.0" but which instead links to the CC BY-NC 3.0 license.)
- While the site ( http://imfdb.org ) clearly has an overall wiki-inspired design and mechanics that leads many to believe it conforms to the same GFDL or CC BY-SA or free content licensing as Commons, that is NOT the case in reality. The problem is twofold:
- The photos taken by the site's admin (MPM2008) are certainly not freely licensed, and this author is known to go to great length to protect his copyrights. Also, it should be noted that not all of his photos carry any watermark and/or any copyright notice. These are certainly not suitable for Commons.
- On the other hand, the site's admins are very lax concerning other people's copyrights-while some files ARE really PD or freely licensed, most (excluding MPM2008's works) are grabbed from random sources (like press images or similar) and in most cases WITHOUT any attribution. It is also a common practice there to overwrite PD or freely licensed files with NON-free files of larger resolution while leaving the former file's attribution notice intact, causing users to believe the new file is also free, when in fact that is not the case...
- 不论是从这两方面的哪一方面来看，这些文件都是100%不适合上传到这里的。
- This site's license prohibits selling, licensing, sublicensing, renting, transfering or distributing of images without alterations. But modified images are free (including using for commercial purposes and using without attributing the original author). There is also no information if the license is revocable.
Mynewsdesk.com
- Mynewsdesk.com is a site for marketers and promotional uploaders. Its default license is a Creative Commons Attribution-ShareAlike license, but this is not adequately understood by their uploaders, who frequently post images for which they do not own the rights to release under the Creative Commons license. Consensus is to avoid using the site.
- Per Commons:Deletion requests/Incorrect PD Netherlands (government works), commercial usage of the images at this site is not allowed. Therefore, though they may seem to be allowable here as government work, they do not fall within Commons scope per COM:SCOPE: Non-allowable licence terms.
- "A community of graphic artists creating and sharing free raw image files!" - that's the slogan. The website is intended as non-commercial but they also allow for CC BY licensing. Regrettably they take their slogan's "creating" with a grain of salt. For example, Vince-Carter-Magic-PSD32033 (and all images shown as related images) are taken from elsewhere, published on other websites. The EXIF of this image states "Copyright Notice: Copyright 2009 NBAE (Photo by Fernando Medina/NBAE via Getty Images)". linksearch
- Photos and videos on Pexels are mostly published under the Pexels Licence which applies non-commercial (NC) restrictions. It also states "Don't redistribute or sell the photos and videos on other stock photo or wallpaper platforms". Therefore Pexels media are ineligible for use on Commons. The Pexels Terms of Service do state that some images were published under a {{Cc-0}} licence — such images would be allowed on Commons, but apparently this only applied to images that were published on Pexels prior to 4 July 2018.
- Appears to consist mostly of uploads by people who do not have the authority to license the copyrights in them, or release the content into the public domain. The website also does not retain good sourcing metadata. Clause 6.1 of the Terms of Use Agreement (last reviewed on 13 June 2011) allows uploaders to mark their files as private or to delete them, which is declared to have the effect of terminating the license for reuse of the files by other people.
- As with fotodatenbank.com, the usage conditions [2] are restrictive:
- Images can be used (...) excluding collections of images or similar where PixelQuelle.de images can be downloaded or bought. (original: (...) "Ausgeschlossen hiervon sind Bilddatenbanken, Bildkataloge oder ähnliche, bei denen PixelQuelle.de Fotos zum Download oder Verkauf angeboten werden.")
- 他们在自己的作品下使用的协议是CC-by-nc-nd授权（既不能商用也不能进行演绎），因此与维基共享资源的协议不相兼容。
- Skyscrapercity (sometimes referred to as SSC) is a forum to which users upload images (often original content, sometimes copyright violations from Flickr etc). No free licensing is required for uploads, so unless compatible licensing is explicitly declared in the forum, or the image is public domain due to age, a VRT email from the copyright holder is required.
- Images sourced from Stock.xchng (sxc.hu) are not allowed on Wikimedia Commons, unless they are explicitly licensed under a free license. Preferably those permissions are recorded in VRTS. All Stock.xchng image that have not been independently released under a free license are subject to speedy deletion since July 1, 2007. See Commons:Deletion requests/Template:Sxc-warning and Template:Sxc-warning for more information.
美国国家实验室
- Although these are commonly assumed to be projects of the Federal Government of the United States, they are actually operated by government contractors and reserve copyrights on their works and may have different terms which might be incompatible with Commons' licensing policy.

- The site claims that you can use any of its images (which are watermarked) as long as references are made to their site.[6] It also does not explicitly allow free modifications of the image, which supposedly means no one can remove their watermark. The key point is that none of the pictures hosted on World Stadiums can be determined to be free of copyright. They do not attribute the authors of the pictures. Most of their photos are copyright violations (taken from forums, official sites, scans of magazines and newspapers, etc): cropped and resized copies of copyrighted images. Others are resized versions of images licensed under Creative Commons ShareAlike, but World Stadiums do not attribute the licensors as required by the license.
