title: on webpage enter, display html browse file dialogue?
body: <p>I have the following code giving a manual browse file dialogue:</p>
  
  <p>input type="file" name="image_file" id="image_file" onchange="fileSelectHandler()"</p>
  
  <p>Is there a way to call this (perhaps using javascript?) automatically on page enter so that the user is given the browse file dialogue upon entering the webpage?</p>
  
  <p>Thanks!</p>
