body: <p>How to check with JS if flash is installed, or not? I don't want to detect the version, or other informations. I want to check only, if it's avaiable, or not.</p>
  
  <p>The swfobject library makes it (and many other things, which are unneccessary for that), but I don't want to use a library for only one function.</p>
