Answer 1

$dir = 'img/';
$images = scandir($dir);
for ($i = 0; $i < count($images); $i++) {
  if ($images[$i] != '.' && $images[$i] != '..') {
    echo '<a href="' . $dir . $images[$i] . '" target="_blank"><img src=' . $dir . $images[$i] . ' style="width: 200px;"></a>';
  }
}

Answer 2

You can create a script in the root of the site and call it through the browser, just don't forget to delete it later.
But for such one-time things it is better to use the php console /bitrix/admin/php_command_line.php?lang=ru
