thanks for rapid response...I should have found that one

 

this works for me commentting out unwanted design features and "hiding" the items the javascript needs to identify

 

<!-- -<fieldset><legend>[[Insert]]</legend>- -->
<table class="normal">
  <tr>
   <!-- -<td width=80>[[Url]]:</td>- -->
   <td><input type="text" id="inp_src" style="display:none" style="width:250px"></td>
   <!-- -<td><button id="btnbrowse">[[Browse]]</button></td>- -->
   <td><button id="btnbrowse" style="display:none">[[Browse]]</button></td>
  </tr>
  <tr>
   <!-- -<td valign="middle" nowrap>[[Alternate]]:</td>- -->
   <td colspan="2"><input type="text" style="display:none" id="AlternateText" size="40" NAME="AlternateText"></td>
  </tr>
  <tr>
   <!-- -<td valign="middle" nowrap>[[longDesc]]:</td>- -->
   <td colspan="2"><input type="text" style="display:none" id="longDesc" size="40" NAME="longDesc"><!-- -<img src="../images/Accessibility.gif"  align="absMiddle" hspace="5">- --></td>
  </tr>
 </table>
<!-- -</fieldset>- -->
