Wikipedia:File copyright tags/Public domain

Most images found on the internet are not in the public domain, even if no explicit copyright information is provided. For an image to qualify as public domain, it must meet specific criteria (see WP:IUP#COPYRIGHT). These include works ineligible for copyright protection by their nature, such as basic designs or ideas, and works that are sufficiently old to have entered the public domain based on their age, such as those created before 1923 in the United States. Additionally, works created by certain government employees as part of their official duties, such as U.S. federal government works, are often considered public domain. Lastly, an image may be in the public domain if the creator or copyright holder has explicitly waived their rights in writing.

For a simple chart on U.S. public domain regulations (Wikipedia servers are located in the U.S. and fall under U.S. guidelines) see the chart here (archived here).

General

Dedications

These tags are used for an author to attempt to release their work into the public domain, disclaiming any copyright. See Wikipedia: Granting work into the public domain.

Art

Intergovernmental

Other countries

Whenever an image is tagged using one of these tags, the image description page should also contain some rationale as to whether and why the image is presumed to be in the public domain in the U.S. and other countries. See also {{PD-US-1996}}, which can be used to state that the copyright on the image was not restored by the URAA.

New Zealand government

Publications of the New Zealand government are mostly covered by Crown copyright, which in New Zealand has a 100-year term under Section 26(3)(b) of the Copyright Act 1994. This puts most recent material out of bounds. However, there is an exception to these provisions for some documents:

New Zealand Crown copyright used to only last 50 years, and copyright has expired for government works from 1944 or earlier. Regular copyright provisions (such as a 50-year term) apply to works by Crown entities and state-owned enterprises, not Crown copyright.
