Images are one of the many types of media used on Wikipedia and may be photos, drawings, logos, or graphs. All images that are used must be legal in the United States, where Wikimedia's servers are located. Images are stored on the Wikipedia website or the partner Wikimedia Commons website. All free content is stored on "Commons" and images that have a copyright 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.
