Laravel Response extend for inline displaying of images

macros.php

<?php

Response::macro('inlineImage', function($path, $name = null, $lifetime = 0)
{
    if (is_null($name)) {
        $name = basename($path);
    }

    $filetime = filemtime($path);
    $etag = md5($filetime . $path);
    $time = gmdate('r', $filetime);
    $expires = gmdate('r', $filetime + $lifetime);
    $length = filesize($path);

    $headers = array(
        'Content-Disposition' => 'inline; filename="' . $name . '"',
        'Last-Modified' => $time,
        'Cache-Control' => 'must-revalidate',
        'Expires' => $expires,
        'Pragma' => 'public',
        'Etag' => $etag,
    );

    $headerTest1 = isset($_SERVER['HTTP_IF_MODIFIED_SINCE']) && $_SERVER['HTTP_IF_MODIFIED_SINCE'] == $time;
    $headerTest2 = isset($_SERVER['HTTP_IF_NONE_MATCH']) && str_replace('"', '', stripslashes($_SERVER['HTTP_IF_NONE_MATCH'])) == $etag;
    if ($headerTest1 || $headerTest2) { //image is cached by the browser, we dont need to send it again
        return Response::make('', 304, $headers);
    }

    $finfo = finfo_open(FILEINFO_MIME_TYPE);
    $mime = finfo_file($finfo, $path);

    $headers = array_merge($headers, array(
        'Content-Type' => $mime,
        'Content-Length' => $length,
    ));

    return Response::make(File::get($path), 200, $headers);
});
