How to copy content from a google doc file that contains tables with images?

I want to use google script to copy content from a source file to a destination file. The source file contains images inside tables. The problem is that the sample scripts I used do not generate the images inside the tables, ie the images that are contained in the tables do not appear in the destination file. Anyone have an idea how to solve this problem? Here is the code used to accomplish this task.

function createDocument() {

  var pastaId = '1NiH5Gk3........';

  var  idPadrao = '1Z-SrW6ocb........';



   var docPadrao = DocumentApp.openById(idPadrao);

  var pasta = DriveApp.getFileById(idPadrao).getParents()

  var body = docPadrao.getBody();


  var docNovo = DocumentApp.create('novoDocTeste1');
  bodyNovo = docNovo.getBody();

  bodyNovo.appendParagraph("This is a testing paragraph.")

  appendToDoc(docPadrao, docNovo);
   var top = docNovo.getBody().getChild(0);
  bodyNovo.insertParagraph(0, "Nome..................");
  salvarArquivo(docNovo, pastaId);


 docPadrao.saveAndClose();
}


function appendToDoc(src, dst) {
  Logger.log('append...');
  for (var i = 0; i < src.getNumChildren(); i++) {
    appendElementToDoc(dst, src.getChild(i));
  }
}

function appendElementToDoc(doc, object) {
  var type = object.getType();
  var element = object.copy();
  Logger.log("Element type is "+type);
  if (type == "PARAGRAPH") {
    doc.appendParagraph(element);
  } else if (type == "TABLE") {
    doc.appendTable(element);
  } 
}

function salvarArquivo(docNovo, pastaId){
  // Get folder by ID
  var folder = DriveApp.getFolderById(pastaId);

    docNovo.saveAndClose(); 

  // Get file by doc id
  var file = DriveApp.getFileById(docNovo.getId());

    // Get root directory
  var parents = file.getParents();

    // Remove file from root folder
  parents.next().removeFile(file);

  // Add file to the specified folder
  folder.addFile(file); 
}
