One more problem: Pop-up window for customized function displays fine in IE, but not open in FireFox. Please advice.

 

The code used for open pop-up window:

 

function insertAnImage(button)
    {
  //use CuteEditor_GetEditor(elementinsidetheEditor) to get the cute editor instance
  var editor=CuteEditor_GetEditor(button);
      var newwin=showModalDialog("intImage.asp?fd=<%=iLink%>&sitename=<%=siteName%>"
   ,editor,"dialogWidth:420px;dialogHeight:500px");
    }
