    $image_path = 'http://' . rawurldecode($path) . '/resources/images/banner/' . $image_name;
    $mime = explode('.', $image_name);

    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");
    header('Content-Type: image/' . $mime[1]);
    header("Content-Disposition: attachment; filename=$image_name");
    header('Content-Transfer-Encoding: binary');
    ob_clean();
    flush();
    readfile($image_path);

你能试试吗？

$image_name = rawurldecode($name);
$image_path = 'http://' . rawurldecode($path) . '/resources/images/banner/' . $image_name;
$mime = explode('.', $image_name);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($image_path));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($image_path));
readfile($image_name);
exit;
