Template:Image class names/doc

This template produces "metadata dummy" (without quotation marks) if the parameter is in a list of placeholder image names and tags contained in this template. It allows suppression of these placeholder images.

Usage

 * class=""

The image parameter can be the image name or a full image tag.

In most cases this template is not called directly, but through image class, see the usage of that template.

Effect
Due to MediaWiki:Monobook.css, containing

@media print { .metadata { display: none } }

the effect of class "metadata" is that by default the image is not printed when using the Monobook skin.

The class "dummy" allows users to use CSS to suppress the display of placeholder images with the CSS: .dummy {display: none}
