This is an information page.

Shortcuts

Images are one of the many types of media used on Wikipedia and may be photos, drawings, logos, or graphs.

All pictures used must be legal in the United States, where Wikimedia's servers are located. Images are stored on the Wiki How website or the partner Wikimedia Commons website. All free content is stored on "Commons" and images that have more onerous copyright restrictions are stored on Wikipedia, under a fair use rationale. Also, images that are used on the Main Page have a local version to prevent vandalism from appearing. Editors can also choose to have a local version stored on Wikipedia.

Images are classified as files and use the prefix of File: or the deprecated prefix of Image:. The File namespace is one of several namespaces used on Wikipedia.

Since Wikipedia is not censored, readers and editors may come across offensive images.
