title: Flash backup image
body: <p>so I have a pretty big flash file on my homepage, which raises a few issues about what to do if the user doesn't have flash player installed on his/her PC.</p>
  
  <p>I would like to make sure that if the user has a old version of flash player, or doesn't have it at all, a backup image will display in place of the flash, how can I accomplish that?</p>
  
  <p>Iss Javascript or jquery an option?</p>
