how to display thumbnail from category using getThumbnailUrl() in Magento

Question

I have bee trying to make this work but had no luck, Basically I need to display the main menu categories on the content block and I did, but now I need to display the thumbnail

Answer 1

Use this below function to display category thumbnail image

   public function getThumbnailImageUrl() 
   {
      $url = false;

      if ($image = $this->getThumbnail()) {

         $url = Mage::getBaseUrl('media').'catalog/category/'.$image;
      }
      return $url;
   }

Then, using for any category :

$_imageUrl=$this->getCurrentCategory()->getThumbnailImageUrl()

you can get the thumbnail image.
