//   from image object ,  not with absolute position.

//

//   argv[0]  : fireworks pop-up menu object

//   argv[1]  : image name or 'this'  ('this' is anchor object )

//   argv[2]  : relative X position

//   argv[3]  : relative Y position 

//

// HOW TO

// step 1. add next source  in your  HTML.

//

//  <script language="JavaScript1.2" src="NN_fw_menu.js"></script>

//

// step 2. change your onMouseOver evnt handler.

// 

//   before : onMouseOver="window.FW_showMenu( fw_menu0,  absoluteX, absoluteY );"

//   after  : onMouseOver="NN_FW_showMenu( fw_menu0,  'imageName', relativeX, relativeY );" or

//            onMouseOver="NN_FW_showMenu( fw_menu0,  this , relativeX, relativeY );"
