Subcategories name and images instead of product for any category in magento?

$layer = Mage::getSingleton('catalog/layer');<br />
$_category = $layer->getCurrentCategory();<br />
$currentCategoryId= $_category->getId();<br />
$_helper = $this->helper('catalog/output');<br />
$cat = Mage::getModel('catalog/category')->load($currentCategoryId);<br />
$children = $cat->getChildren();<br />
$_subCate =  explode(",",$children);<br />

foreach($_subCate as $category):<br />
   $subcategory = Mage::getModel('catalog/category')->load($category);<br />
   if($subcategory->getIsActive()):<br />
<a href="<?php echo $subcategory->getURL() ?>" <br/>title="<?php echo $this->htmlEscape($subcategory->getName()) ?>" class="cats"> <br />
  <img src="<?php echo $subcategory->getImageUrl() ?>" width="200" height="200" alt="<?php echo $this->htmlEscape($subcategory->getName()) ?>" /><br />
   </a><br /><?php endif; ?><br /><br />

You have to use your own styles to show subcategory image and name. I show on my sites as subcategory image is on top and at bottom of this it’s name printed.

Hope you can understand this. If you have any problem please do write me in comments.
