          Are you running the slideshow as local files?&nbsp;
          If so, the URL in the address bar starts with "file:" instead 
          of "http:"&nbsp;
          For security reasons, some browsers disallow this.&nbsp;
          You may have to push your entire slideshow to a remote server.&nbsp;
          Or access it locally via a locally installed web server.
          <table>
            <tr>
              <td style='width:4rem' valign='top'>
                Hint:
              </td>
              <td valign='top'>
                In Firefox, you can use local files if you change the option
                "privacy.file_unique_origin" to false in about:config.&nbsp;
                Don't forget to change it back afterwards!
