This page explains the image syntax when editing the wiki. You or another user must usually upload an image before you can use it on a page. Images that are stored on a MediaWiki server are usually rendered by using the File: namespace prefix but the legacy Image: namespace prefix is still supported as a synonym as the target of a MediaWiki link. The alternate Media: namespace prefix is also usable to reference the original media file content for rendering or downloading it separately, out of any MediaWiki page.

Wikipedia:How to upload a photo - Wikipedia
If an article already has an infobox at the top right, then the usual place for the article's first picture is within the infobox. This page describes how to add that picture. Confusingly, the proper syntax to do this varies from one infobox to another. This page assumes that the picture has already been uploaded to Wikipedia or to Wikimedia Commons ; see Wikipedia:Uploading images.

Thank you for offering to contribute an image or other media file for use on Wikipedia. This wizard will guide you through a questionnaire prompting you for the appropriate copyright and sourcing information for each file. Please ensure you understand copyright and the image use policy before proceeding.
Adding images helps improve the quality of any given article, providing additional details and illustrating the subject - after all, a picture speaks a thousand words! The process of adding images to an article is very similar to adding videos. You can brush up on our video embed tool to complete your mastery of the tools of a wiki illustrator. Both anonymous and registered users can add images to an article in source text editing mode. In visual editors, only registered users can.
