{{anchor|File in use in another Wikimedia project}}{{anchor|in use}} ==== File in use in another Wikimedia project ==== A media file that is in use on one of the other projects of the Wikimedia Foundation is considered automatically to be useful for an educational purpose, as is a file in use for some operational reason such as within a template or the like. Such a file is not liable to deletion simply because it may be of poor quality: if it is in use, that is enough. An otherwise non-educational file does not acquire educational purpose solely because it is in use on a user page (the "User:" namespace) of another project, but by custom the uploading of small numbers of images (e.g. of yourself) for use on a personal user page of another project is allowed. It should be stressed that Commons does not exist to editorialise on other projects – that an image is in use on a non talk/user page is enough for it to be within scope.
{{anchor|File in use on Commons only}} ==== File in use on Commons only ==== An otherwise non-educational file does not acquire educational purpose solely because it is in use on a gallery page or in a category on Commons, nor solely because it is in use on a user page (the "User:" namespace), but by custom the uploading of small numbers of images (e.g. of yourself) for use on a personal user page on a Wikimedia Foundation project is allowed. Files relating to projects or events of the Wikimedia Foundation are also allowed (e.g. photographs of user meetings).
{{anchor|File not legitimately in use}} ==== File not legitimately in use ==== A media file which is neither: * realistically useful for an educational purpose, nor * legitimately in use as discussed above falls outside the scope of Wikimedia Commons. The emphasis here is on realistic utility, either for one of the Wikimedia projects or for some other educational use. Not all images for example are realistically useful for an educational purpose, and an image does not magically become useful by arguing that "\'\'it could be used to illustrate a Wikipedia article on X\'\'", where X happens to be the subject of the file. For example, the fact that an unused blurred photograph could theoretically be used to illustrate an article on "Common mistakes in photography" does not mean that we should keep all blurred photographs. The fact that an unused snapshot of your friend could theoretically be used to illustrate an article on "Photographic portraiture" does not mean that we should keep all photographs of unknown people. The fact that an unused pornographic image could theoretically be used to illustrate an article on pornography does not mean that we should keep low quality pornographic images (see also [[#Censorship|Censorship]]).
{{anchor|Examples}} ==== Examples ==== Examples of files that are not realistically useful for an educational purpose: * Private image collections, e.g. private party photos, photos of yourself and your friends, your collection of holiday snaps and so on. There are plenty of other projects on the Internet you can use for such a purpose, such as [[w:Flickr|Flickr]]. Such private image collections do not become educational even if displayed as a gallery on a user page on Commons or elsewhere. * Artwork created by the uploader without obvious educational use. * Files apparently created and/or uploaded for the purpose of vandalism or attack. Preexisting designs and symbols that are or have been associated with nationalistic, religious or racist causes are not out of scope solely because they may cause offence. Provided they are legal to host and otherwise fall within Commons scope (e.g. if they could for example be used to illustrate a Wikipedia article on a hate group) they should be kept. * Advertising or self-promotion. * Files that add nothing educationally distinct to the collection of images we already hold covering the same subject, especially if they are of poor or mediocre quality.
{{anchor|Discussion}} ==== Discussion ==== We hold many high quality images of species-identified birds, and there is no realistic educational use for a small, blurry, poorly composed snapshot of an unidentified and unidentifiable bird. Of course, there is always room for another educationally distinct image, for example illustrating some aspect of bird behaviour that we do not currently cover, even if the image is perhaps not of the highest quality. There may sometimes be an argument for retaining multiple images that are (from an educational point of view) quite similar, for the sake of variety and availability of choice, but there is no purpose in our hosting many essentially identical poor quality images that have no realistic educational value. New educational files of exceptional quality are always welcome, and the later uploading of such files may in principle render earlier unused poor quality files educationally redundant. However, as indicated above, a file that is used in good faith on a Wikimedia project is always considered educational, so a poor quality file that remains in use is not liable to deletion even if a better-quality file covering the same subject later becomes available. New and existing files of poor or mediocre quality may or may not be realistically useful for an educational purpose depending on what they illustrate and what other files we have of the same subject. Where a subject is rare and/or difficult to capture, even a poor quality file may be of significant educational value, especially if Commons has very few or no similar files already. On the other hand, poor or mediocre files of common and easy to capture subjects may have no realistic educational value, especially if Commons already hosts many similar or better quality examples. Image quality is just one of the factors that may limit the educational usefulness of a file. Other limiting factors may include low-resolution and hard-to-remove watermarks.
