Instructions for {{Hidden image}}
{{Hidden image}} is a template that adds an invisible image to a page. That is, the image is on the page, but is invisible on both desktop and mobile. The reason for this is so that pages that don't have a suitable in-universe image that can be added to the page normally can still have an image for display in areas such as category pages (using the "dynamic" view).
Usage is simple: {{Hidden image|file name}}. "file name" should be given without the "File:" namespace prefix but with the file extension. For example,
{{Hidden image|First Doctor Cameca.jpg}}
