    $("#clearBackgroundEdit").remove();
  }
   }

   JS.load(function() {
   JS.addListener("click","editProfileButton",editProfile);
   })

The iframe is loading to the right page, but no post data is being sent to the page. I've been banging my head agasint the desk for about 6 hours now, not a single clue what I might be missing and or be doing wrong. The goal here is to send the post $_FILE to the profilePhotoUpload.php page so my PHP script can then handle the request. But again, no post data is making it to the page.

Thanks for any help you may have got.
