  Version:     1.5.4
  Description: Selects a random image from a specified folder, and provides
               methods for using it.  Current supported methods generate an

?>

В шаблон в место вывода вписывается <?php if (function_exists('generateRandomImgTag')) { generateRandomImgTag(); } ?>

Скрипт выводит случайную картинку из дериктории и по умолчанию прописывает ей alt=имя файла картинки - переменная $image_filename (правится в самом конце кода)
Как сделать так чтобы в этом поле выводилось то что указано в качестве ключевых слов или заголовка статьи отображаемой в данный момент ... ??
