Is there any way to add an array photo when finish upload photo in message? and how to make it work?

My code is working. but, I don’t know is this the right thing to do or not.
for my code I just excuse it every and adding new class.

  var d = new Date();
  var randTime = d.getTime(); // random date class for photo browser
  messages.addMessage({
    type: 'sent',
    text: '<a href="#" class="pb'+randTime+'"><img src="' + imgUrl + '" height="100"></a>',
  }, 'append', false);
  var photos = [
    imgUrl
  ];
  /*=== Standalone Dark ===*/
  var myPhotoBrowserDark = app.photoBrowser.create({
    photos,
    theme: 'dark'
  });
  $$('.pb'+randTime).on('click', function () {
    myPhotoBrowserDark.open();
  });
