It is unclear to me how to detect preliminarly the availability of the 
plugin, or which syntax to use to have a fallback to a preview image.
I am a bit puzzled with this idea, it sounds good but I would greatly 
appreciate a hint.
My basic code is something like this:
...
var oldNode=document.getElementById("doc")
var newNode=document.createElement("embed")
newNode.type="application/pdf"
newNode.src="http://"+location.host+"/images/test.pdf"
oldNode.parentNode.replaceChild(newNode,oldNode)
newNode.id="doc" // ready for another substitution - same id as previous
...
then I resize the div container etc.
So... what kind of feature must I look for?
Many thanks
Dan
