产品图像显示在产品列表和特色产品页面中，但不显示在magento的详细页面中

This is the part of code that calls the media.phtml

    <div class="product-img-box">

        <?php echo $this->getChildHtml('media') ?>

    </div>

I have checked this on frontend and found that nothing come between these div, thats why the images are not displayed in detail page. I have checked and run same code on localhost its working. But not working on live site. Can any one tell are fix my problem.

Thanks in advance.

Have you marked Radio button for product image as Base Image in Administration area on live site? This radio button causes to display the product image on Product detail Page. please check.
