Files uploaded to Commons should be free both in the country of origin (as defined by the Berne Convention) and in the United States of America, and possibly in other countries involved, either through being properly licensed by the copyright owner or being in the public domain.
- 主页面: 共享資源:各種題材的著作權法規。
共享資源:各種題材的著作權法規 brings together a variety of subjects and aims to answer the question "Can I upload photographs/pictures of ...?"
- Generally, photos you have taken yourself of uncopyrightable subjects such as views; nature; yourself; and people who have given their consent for you to photograph them and for you to publish the photograph. (However, you should remember that uploads should be educational - Commons is not your private web space.)
- Photos taken by you, or scans or photocopies made by you of objects or designs whose copyright has expired (usually 70 years after the death of the author, but see 共享资源:各地著作权法规 for a country-by-country list).
- Mere mechanical scans or photocopies, made by somebody else, of an object or design old enough to be in the public domain (usually 70 years after the death of the author, but see 共享资源:各地著作权法规 for a country-by-country list). For scans of old images that may have been enhanced, see 共享資源:何時使用PD-scan標籤.
- Photographs, taken either by yourself or someone else, that are faithful reproductions of 2D public domain works of art. See 共享資源:何時使用PD-Art標籤.
Other subjects may or may not be allowable - see headings at 共享資源:各種題材的著作權法規. If you want to have an answer to the question "Can I upload photographs/pictures from ...?", see the section at 共享資源:各種題材的著作權法規 on Internet images. See also: 共享资源:原创门槛.
Let's assume you took a picture with your camera, or you've scanned it from somewhere, or you've downloaded it off a web server - and want to upload it to Wikimedia Commons. How do you know what's OK and what's not? Here's a simple chart that helps you decide. In cases of doubt, read the further advice for your country first. If you still don't know for sure, ask on Commons:Help desk or Commons:Village pump/zh in your local language.
See 共享資源:各種題材的著作權法規 for a more complete list.

Laws about copyright differ from country to country. Images uploaded to Commons, unless uploaded from the United States, involve the interaction of two or more copyright jurisdictions. The laws of individual countries differ especially in the following points:
- The time for which a copyright applies. In most countries, copyright expires no later than 70 years after the death of the author (p.m.a.). There may be special terms for recently published old material.
- Status of works of the government. In many (but not all) countries, documents published by the government for official use are in the public domain.
- Material applicable for copyright. In some jurisdictions, pictures of artistic work like architecture, sculptures, clothing etc. can not be used freely without the consent of the creator of the original artwork.
Almost all countries in the world are party to the Berne Convention for the Protection of Literary and Artistic Works (see here for the text). Following this convention, countries enforce copyrights from other countries, according to certain rules. One consequence of these rules is that we should always care about the laws of the country of origin of the work.
Dealing with uncertainty
When the date is unknown
Assume the most recent possible date considering the subject. The photo here shows Albert Einstein and his wife Elsa. Elsa died on December 20, 1936; Albert later on April 18, 1955. Therefore, it was taken before December 20, 1936.
Assume the most restrictive reasonably possible location considering the subject. In the Einstein photo here, it could be the United States, Germany, the Atlantic Ocean (assuming the Einstein couple was on board a ship) or any other country or location he reasonably could have gotten a photo taken in, but it would not likely be Nepal, for example.
When the photographer is unknown
Assume the most reasonable restrictive copyright barring evidence to the contrary. That is, unless the site or source itself asserts a freer set of rights (and you have good reason to believe they are not misapplying rights they do not have) assume the photographer retained all rights he legally could in his jurisdiction.
But the Berne Convention says that photographs are in the public domain 50 years after publication if the photographer is unknown. This applies unless a country has made a specific law.
Assume that the author of the image on the right is unknown to us, but not unknown in the copyright sense. We know that the image represents the ship Borda, which was scrapped in 1891. The image could have been taken that year by a 20-year-old man, who could die of old age in his 90s; this brings us to 1960. Assuming the normal terms for "works" apply and a 70-year long copyright term pma, the image would be covered by copyright until the 2030s. If the work was truly anonymous, then the copyright probably did not exceed 1891 + 70 = 1961, which means it is free if it was published before 1927 (or free in USA for other reasons).
Caution, not being able to find an author does not mean that the work is anonymous. It can mean that we did not search long enough or at the right place.
