Llwybr(au) brys:

Mae'n bosibl y dilëir delweddau sydd ar Wicipedia os nad ydynt yn cyd-fynd â'n polisi defnyddio delweddau ni, neu os nad oes angen ohonynt ragor. Diben y dudalen hon ydy darparu trosolwg i ddulliau gweithredu dileu delweddi neu werthuso eu cadw. Os oes cwestiwn arbennig gennych, dylech ofyn ar y dudalen bolisi mwyaf addas i'r ymholiad. Gweler isod am feini prawf dileu delweddi.

Tra bo llawer o resymau dros ddileu delweddi, achos pryder mwyaf Wicipedia ydy ein hawl cyfreithlon i'w dangos. Os ydych yn credu y dylai ddileu delwedd oherwydd hawlfraint, trwyddedu neu gydymffurfiad â chanllawiau cynnwys nad ydynt yn rhydd, gweler "Pryderon hawlfraint" isod. Manylir problemau nad ydynt yn gysylltiedig â hawlfraint neu drwyddedu o dan "Pryderon eraill".

Meini prawf dileu delweddi[golygu cod]

Cyffredinol[golygu cod]

G1. Dwli.
Testun digyswllt neu ddwli/lol yn unig. Eithriad i hyn ydy ysgrifennu blêr, sylwadau anllad, theorïau twp, fandaliaeth a phranciau, cynnwys ffuglennol, a chynnwys nad yw'n Gymraeg dealladwy. Eithriad i hyn ydy'r blwch tywod a thudalennau sydd yn enwle'r defnyddiwr.
G2. Test pages.
A page created to test editing or other Wikipedia functions. Subpages of the Wikipedia Sandbox created as tests are included, but not the Sandbox itself. This criterion does not apply to pages in the user namespace, nor does it apply to valid but unused or duplicate templates (although criterion T3 may apply).
G3. Pure vandalism and blatant hoaxes.
This includes blatant and obvious misinformation, blatant hoaxes (including images intended to misinform), and redirects created by cleanup from page-move vandalism.
G4. Recreation of a page that was deleted per a deletion discussion.
A sufficiently identical and unimproved copy, having any title, of a page deleted via a deletion discussion. This excludes pages that are not substantially identical to the deleted version, pages to which the reason for the deletion no longer applies, and content moved to user space for explicit improvement (but not simply to circumvent Wikipedia's deletion policy). This criterion also excludes content undeleted via deletion review, or which was deleted via proposed deletion or speedy deletion (although in that case the previous speedy criterion, or other speedy criteria, may apply).
G5. Creations by banned or blocked users.
Pages created by banned or blocked users in violation of their ban or block, and which have no substantial edits by others.
G6. Technical deletions.
Uncontroversial maintenance, such as deleting dated maintenance categories, deleting unnecessary disambiguation pages, or performing uncontroversial page moves. This also includes pages unambiguously created in error and/or in the incorrect namespace. If no special tag like {{db-move}} can be used and the reason for deletion is not self-evident, a reason for deletion should be supplied on the talk page or in the edit summary.
G7. Author requests deletion.
If requested in good faith and provided that the only substantial content to the page and to the associated talk page was added by its author. (For redirects created as a result of a pagemove, the mover must also have been the only substantive contributor to the pages prior to the move.) Note that this does not apply to user talk pages, which are not deleted except under very exceptional circumstances: see WP:DELTALK. If the sole author blanks a page other than a userspace page or category page, this can be taken as a deletion request.
G8. Pages dependent on a non-existent or deleted page.
Such as talk pages with no corresponding subject page; subpages with no parent page; image pages without a corresponding image; redirects to invalid targets, such as nonexistent targets, redirect loops, and bad titles; and categories populated by deleted or retargeted templates. This excludes any page that is useful to Wikipedia, and in particular: deletion discussions that are not logged elsewhere, user talk pages, talk page archives, plausible redirects that can be changed to valid targets, and image pages or talk pages for images that exist on Wikimedia Commons. Exceptions may be sign-posted with the template {{G8-exempt}}.
In certain cases, G8 can be used even if the depending page still exists, i.e. if the deletion of the page has already been decided by consensus or the page clearly meets a criterion for speedy deletion and is tagged as such.
G9. Office actions.
The Wikimedia Foundation office reserves the right to speedily delete a page temporarily in cases of exceptional circumstances. Deletions of this type should not be reversed without permission from the Foundation.
G10. Pages that disparage, threaten, intimidate or harass their subject or some other entity, and serve no other purpose.
These "attack pages" may include libel, legal threats, material intended purely to harass or intimidate a person or biographical material about a living person that is entirely negative in tone and unsourced. These pages should be speedily deleted when there is no neutral version in the page history to revert to. Both the page title and page content may be taken into account in assessing an attack. Articles about living people deleted under this criterion should not be restored or recreated by any editor until the biographical article standards are met.
G11. Unambiguous advertising or promotion.
Pages that are exclusively promotional, and would need to be fundamentally rewritten to become encyclopedic. Note: An article about a company or a product which describes its subject from a neutral point of view does not qualify for this criterion.
G12. Unambiguous copyright infringement.
Text pages that contain copyrighted material with no credible assertion of public domain, fair use, or a free license, where there is no non-infringing content on the page worth saving. Only if the history is unsalvageably corrupted should it be deleted in its entirety; earlier versions without infringement should be retained. For equivocal cases (such as where there is a dubious assertion of permission, or where free-content edits overlie the infringement), please consult Wikipedia:Copyright violations.

Remember to check that the suspected source of the seemingly unambiguous copyright violation is not in fact free content, such as a Wikipedia mirror, and to notify the page's creator when tagging a page for deletion under this criterion; the template {{nothanks-sd}} is available for this. For images and media, see the equivalent criterion in the "Files" section below, which has more specific instructions.

Deleting images[golygu cod]

To actually delete an image, you must be an administrator. To do so, go to the image description page and click "delete" at the top of the page (it may be located elsewhere if you are using a skin other than monobook). Deleted images can now be undeleted.

Only images on Wikipedia can be deleted through these processes. If an image is hosted on Wikimedia Commons, it must be deleted there. Please see Commons:Deletion policy. If an image is available at both Wikipedia and Wikimedia Commons, and it is deleted here, it's a good idea to also bring it up for deletion on Commons, as their inclusion policies are generally much stricter than those of the English Wikipedia.

Copyright concerns[golygu cod]

Images and photographs, like written works, are subject to copyright. Any work created in the United States since 1978 is automatically copyrighted unless it has been explicitly placed in the public domain, and this also applies to most other nations in the world today. Many older works are copyrighted as well. Most images found on the Internet need to be licensed directly from the copyright holder or someone able to license on their behalf. In some cases, fair use guidelines may allow an image to be used irrespective of any copyright claims. Image description pages must be tagged with a special tag to indicate the legal status of the images, as described at Wikipedia:Image copyright tags. Untagged or incorrectly-tagged images will be deleted.

If you are uncertain of the copyright status of an image that you would like to use or have concerns about an existing image that are insufficient to prompt action as set forth below, you may seek feedback at media copyright questions.

Addressing suspected copyright infringement[golygu cod]

If you encounter an image that is indisputably non-free, and it can comply with our non-free content policy, be bold and retag it as a non-free image with an appropriate tag. Otherwise:

For images claimed under free license[golygu cod]

  • If the image lacks a source, so copyright status cannot be determined, follow the usage directions at Template:Di-no source. Note that editors sometimes specify such information in the upload summary, so be sure to check the circumstances of the image.
  • If the image lists a source with no evidence of permission, such as release at the source website or OTRS ticket number, follow the usage directions at Template:Di-no permission. This does not apply to images where the uploader claims to be the copyright holder.
  • If a copyright infringement is blatant—that is, if the image is claimed under a free license when this is obviously not the case—it may be tagged for speedy deletion under speedy deletion criterion F9. This does not include images used under a claim of fair use, nor does it include images with a credible claim that the owner has released them under a Wikipedia-compatible free license. Those may, instead, be handled by one of the processes below. This does include images from stock photo libraries such as Getty Images or Corbis.
    • Tag the image with {{db-f9|url=original source}}, replacing "original source" with the URL where the image may be found. No further action is mandatory, but it is a courtesy to notify the contributor. The tag will generate a notice which may be easily pasted onto the user's talk page.
  • If a copyright infringement is not blatant—that is, if you dispute the source or licensing information, but further investigation may be necessary to confirm infringement—it should be listed for review at possibly unfree files.
    • Tag the image with {{puf}}. Directions for using this tag are found at Template:Puf. Be sure that you follow through after tagging the image by notifying the contributor and listing the image at the possibly unfree images page as directed at that template. You may wish to monitor the conversation there in case your further input may be helpful in resolving the issue. Images are listed at that page for 14 days before they are processed.

For images of uncertain or restricted license[golygu cod]

If the image:

  • is a user-created image, consider whether it can be properly brought into compliance with our non-free content policy. If it can, it is suggested to use the Nodyn:Tls template.
  • lacks a license, follow the directions at Template:Di-no license. Note that editors sometimes specify such information in the upload summary, so be sure to check the circumstances of the image.
  • is not truly public domain or licensed under GFDL or an appropriate Creative Commons license and claims non-commercial use, non-derivative use or used with permission, if it was uploaded after May 19, 2005 or is not used in any articles, you may tag it with {{Db-f3}}, but first consider whether it can be properly brought into compliance with our non-free content policy. If it can, please provide a fair use tag and a fair use rationale, also adding {{Non-free with NC}} to images licensed for non-commercial use.

For images claimed under fair use[golygu cod]

For fair use images:

Be sure to check the template that will appear on the image after tagging to see if additional steps, such as notifying the contributor, are necessary.

Other concerns[golygu cod]

Speedy deletion[golygu cod]

There are several circumstances unrelated to copyright which may result in an image being speedily deleted. These include, but are not limited to:

  • redundant image. If an image is a redundant copy of an image:
    • on Wikipedia, in the same file format, and at the same or lower quality/resolution, and all inward links have been updated, follow the usage directions at Template:Db-f1.
    • at Wikimedia Commons, under the same name, and it satisfies the additional conditions set out at WP:CSD#F8, follow the usage directions at Template:Db-f8.
  • image corruption. If an image is corrupt or empty, follow the usage directions at Template:Db-f2.
  • file format. If the file is not an image, sound or video file (this includes .doc, .pdf and .xls files) and it has no foreseeable use in the encyclopedia, tag the image with {{db-f10}}.

Deletion discussions[golygu cod]

For other concerns that may require deletion of an image, including if the image is unneeded, Wikipedia:Images and media for deletion should be used. Please follow the instructions there for listing the image for review. Images that have been listed there for more than 5 days are eligible for deletion if either a consensus to do so has been reached or no objections to deletion have been raised.

Mass nominations[golygu cod]

Users may feel attacked or demoralized when a large number of their uploads are nominated for deletion all at once. They may feel that the result is fait accompli because they are unable to thoughtfully respond to so many nominations in a short period. In situations where a larger number of images uploaded in good faith by a single user, or multiple images from the same group of articles, need to be tagged for deletion, nominators should consider ways of softening the impact on the editors affected. This may include:

  • Inititate a discussion with the affected users before making the nominations
  • Avoid rapid repetitions of templated notification messages on their talk pages (e.g. through automated nomination scripts)
  • Choose carefully between group nominations (several file in the same deletion discussion) or multiple individual nominations. The former are more efficient for groups of cases that fall under the exact same criteria, the latter for groups of cases that are different enough to require individual scrutiny.
  • Consider only nominating a limited number at a time. If these cases turn out to be contested, consider waiting until the first group of deletion discussions has concluded before making more nominations.
  • If the cases in question are representative of a more general problem, consider opening a discussion at Wikipedia talk:Non-free content or Wikipedia:Administrators' noticeboard/Incidents to gain wider feedback and provide the users a fair opportunity to respond.

Undeletion requests[golygu cod]

Non-controversial undeletions may be requested at Wikipedia:Requests for undeletion. This includes images which were being deleted for licensing reasons, when a user is prepared to provide correct licensing information, or when there is a need for a file which was previously deleted as orphaned and non-free.

For undeletions that are not non-controversial, a suggested first step in requesting undeletion is to approach the deleting administrator. The administrator should be courteously invited to take a second look at the issue. If the matter cannot be resolved through conversation with the deleting administrator, undeletion requests should be brought to deletion review.
