Скачивает пустые картинки!

Устал рабирался скачивает пустые картинки парсер и все тут как не тыкал так понять не смог почему! Function:

А вот собственно и исполняющий файл:

<?php
    include 'multi.php';
    $x = 'C:\srv\OpenServer\domains\conell-ru\published\publicdata\U0010117NEW\attachments\SC\products_pictures\1';
    $folder = substr($x, 0,-1);
    $file = file('C:\srv\OpenServer\domains\parsers\linkimg.csv');
    $fl = array();
    foreach ($file as $ms) {
        $a = str_replace("\n", '', $ms);
        $b = str_replace('"', "'", $a);
        $fl[] = $b;
    }
    echo count($fl)."\n";
    $param = array();
    foreach ($fl as $dan){
        $jpg = explode(';', $dan);
        $away = $folder.str_replace("/", '', $jpg[1]).'.jpg';
        $param[$jpg[0]]= $away; 
    }
    $urls = array_chunk($param,1);
    foreach ($urls as $key) {
        if(_batchDownload($key) == true){
            echo 'download complete'."\n";
        }
        else{
            echo 'error complete'."\n";
        }

    }
