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.
