From Lostpedia

This is an extension I wrote for MediaWiki to insert polldaddy.com flash polls into Lostpedia. It was originally based off of Sylvain Machefert's googlevideo and youtube video extensions, but has been re-written to use parameters within the tag to make it more elegant and secure.

Usage: <polldaddy pollid="12345" width="252" height="372" />

Using the flash code from the polldaddy.com website:

<embed allowScriptAccess="never"  saveEmbedTags="true" src="http://www.polldaddy.com/poll.swf"
FlashVars="p=12345" quality="high"  wmode="transparent"  bgcolor="#ffffff" width="252"
height="372"  name="beta3" salign="tl" scale="autoscale"  type="application/x-shockwave-flash"
pluginspage="http://www.macromedia.com/go/getflashplayer" ></embed>

Use this tag in Mediawiki:

<polldaddy pollid="12345" width="252" height="372" />

Here's the code:
