过滤器Magento产品集合的产品与图像

Question

我有一个产品集合，我从一个可配置的产品，我想过滤该集合，只包括有图像附加到他们的产品。我如何去做这件事？

代码看起来是这样的：

$configurableProduct = $this->getConfigurableProduct(); 
$childProducts = $configurableProduct->getTypeInstance()->getUsedProductCollection(); 

// add some filter here to get only products with images 
$childProducts->addAttributeToFilter(/* what goes here? */);  

foreach($childProducts as $product) { 
    ... 
} 

任何帮助表示赞赏。谢谢！ 乔
