If I link to an internal PDF file in Media Wiki, how can I prevent thumbnail display for PDFs?
<p>With a syntax like this ...</p>

<pre><code>[[File:foo.pdf]]
</code></pre>

<p>... it is possible to refer to a file in a MediaWiki page. In this case a thumbnail is generated from the first PDF page and displayed in the rendered view of the page.</p>

<p>My question is: How do I prevent this thumbnail generation and present some PDF specific icon instead? (A single icon for all PDF files?)</p>
