title: How to check if there is macromedia flash player installed on browser?
body: <p>I am using uploadify plugin to upload images. On some browsers uploadify button is not shown because of unavailability of macromedia flash player, I guess.</p>
  
  <p>Is there any way to check if there is macromedia flash player installed, If not then show a link to download flash player at the place of upload button. </p>
  
  <p>Thanks </p>
