все файлы из папки images закинул в корень шаблона и в запись вставил код:

<a href="#" class="a-btn">
    <span class="a-btn-symbol">Z</span>
    <span class="a-btn-text">Download Now</span>
    <span class="a-btn-slide-text">Windows Vista / Windows 7</span>
    <span class="a-btn-slide-icon"></span>
</a>

не понял правда какие значения прописывать, и вот что получилось Пробная страница
