Tengo problemas con la librería Dropzone al insertar imagen en la base de datos, el código que tengo es el siguiente[Unanswered]

Este es el código para insertar varias imágenes mediante dropzone que se llama imagenes_add_multiple.php y el siguiente se llama upload.php, alguien me pudiera ayudar, cuando abro el archivo imagenes_add_multiple.php me lista todas la imagenes correspondientes a una nota mediante el $refProducto = $_GET["recordID"], pero si agrego solo una imagen la graba en la base de datos y en la carpeta correspondiente mediante time() para que su nombre no se repita, el tema es cuando quiero insertar dos imágenes al mismo tiempo, graba una sola imagen en la carpeta, pero dos entradas en la base de datos con el mismo nombre, o sea lo duplica. Si me pudieran orientar, estaría muy agradecido, saludos a todos.

imagenes_add_multiple.php

<?php

  // For security, start by assuming the visitor is NOT authorized. 
  $isValid = False; 

  // When a visitor has logged into this site, the Session variable MM_Username set equal to their username. 
  // Therefore, we know that a user is NOT logged in if that Session variable is blank.

    // Besides being logged in, you may restrict access to only certain users based on an ID established when they login. 
    // Parse the strings into arrays.
