通过重写Magento 的 Product 模块属性，来达到同时删除产品和图片的功能

新建个文件 app/code/local/Mage/Catalog/Model/Product.php，

复制 app/code/core/Mage/Catalog/Model/Product.php 文件里的代码，

将原有的delete函数:

    public function delete()
    {
        parent::delete();
        Mage::dispatchEvent($this->_eventPrefix.'_delete_after_done', array($this->_eventObject=>$this));
        return $this;
    }

替换成：

    public function delete() {
        foreach ($this->getMediaGallery('images') as $image) {
            $image_path = $this->getMediaConfig()->getMediaPath($image['file']);
            if (file_exists($image_path)) {
                @unlink($image_path);
            }
        }
        parent::delete();
        Mage::dispatchEvent($this->_eventPrefix . '_delete_after_done', array($this->_eventObject => $this));
        return $this;
    }

保存，并重新刷新缓存即可。
