how to insert record repeatedly

I would like your orientation, I'm doing an insertion to my database of images that I upload, everything inserted very well, only that I do not repeat the name of this image entered the same number of times as the images entered.

What can I be doing wrong?

foreach($_FILES as $file)
{
// some information about image we need later.
$ImageName      = $file['name'];
$ImageSize      = $file['size'];
$TempSrc        = $file['tmp_name'];
$ImageType      = $file['type'];


        //$idit=$_POST['id_item'];
        //$itdesc=$_POST['item_descripcion'];
        //$pvent=$_POST['precio_venta'];
        //$idpgo=$_POST['id_pago'];
        //$gp=$_POST['grupo'];
        //$asign=$_POST['asignatura'];
        //$pnomb=$_POST['plan_nombre'];

if (is_array($ImageName)) 
{
    $c = count($ImageName);

    echo  '<ul>';

    for ($i=0; $i < $c; $i++)
    {
        $processImage           = true; 
        $RandomNumber           = rand(0, 9999999999);  // We need same random name for both files.


         //aqui declaro el nombre a insertar
        $nmb=$_POST['nombre_item'];

        if(!isset($ImageName[$i]) || !is_uploaded_file($TempSrc[$i]))
        {

            echo '<div class="error">Un error a ocurrido al procesar el Libro <strong>'.$ImageName[$i].'</strong>, Verifique que el archivo no exceda los '.$BigImageMaxSize .'MB!</div>'; //output error
        }
        else
        {
            //Validate file + create image from uploaded file.
            switch(strtolower($ImageType[$i]))
            {
                case 'image/png':
                    $CreatedImage = imagecreatefrompng($TempSrc[$i]);
                    break;
                case 'image/gif':
                    $CreatedImage = imagecreatefromgif($TempSrc[$i]);
                    break;

                case 'image/pjpeg':
                    $CreatedImage = imagecreatefromjpeg($TempSrc[$i]);
                    break;
                default:
                    $processImage = false; //image format is not supported!

            }
            //get Image Size
            list($CurWidth,$CurHeight)=getimagesize($TempSrc[$i]);

            //Get file extension from Image name, this will be re-added after random name
            $ImageExt = substr($ImageName[$i], strrpos($ImageName[$i], '.'));
