Template:Imageexists

Syntax time:

{{imageexists
|file    = filename.png
|width   = 256px
|caption = derp
|mcat    = Missing images
}}

Usage: Given file (the only real required attribute), will either show that file, or (if it doesn't exist) a placeholder that links to the file uploader, pre-set for that filename. Upon uploading it the image will display the new upload.

• width: width of uploaded image (note that the placeholder will always be normal size)
• caption: Wit.
• mcat: The category to place the page into when the file does not exist.
