I am using magento 1.7 version.I have some images with product.Now I want to show as a slider in detail page.my code is below:-

<?php if (count($_product->getMediaGalleryImages()) > 0): ?>  
<div class="more-views">

<div class="productsmallImage">
    <div id="slider2">
        <a class="buttons prev" href="javascript:;">left</a>
        <div class="viewport">                 
            <ul class="overview">            
                <?php foreach ($_product->getMediaGalleryImages() as $_image):?>
                <li>
                    <!--No lightbox on click of image-->
                  <a href="<?php echo $_image->getUrl();?>" title="<?php echo $_image->getName();?>" onclick="$('image').src = this.href; return false;">
                      <img src="<?php echo $_image->getUrl(); ?>" width="56" height="56" alt="<?php echo $this->htmlEscape($_image->getLabel()) ?>" />
                  </a>
                </li>
                <?php endforeach; ?>
            </ul>
        </div>
        <a class="buttons next" href="javascript:;">right</a>
    </div>
</div>

In this count($_product->getMediaGalleryImages()) has value 4.All the images showing but need to resize them.Please help to do this.

Solution

Try to use the following construction for images output:

<img src="<?php echo $this->helper('catalog/image')->init($_product, 'thumbnail', $_image->getFile())->resize(56) ?>" alt="<?php echo $this->htmlEscape($_image->getLabel()) ?>" />
