前端产品图片来自此path1：
media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/i/m/img24.jpg
后端产品图片来自此path2
media/catalog/product/i/m/img24.jpg
为什么相同的图像存储在不同的路径中。
我认为后端图像是从正确的路径提供的，我希望前端图像也可以从同一路径发出。
所以我们按照link＆amp;在下面的文件中添加了以下代码，但之后我们的网站没有加载任何图片：
app/code/core/Mage/Catalog/Helper/Image.php
echo Mage::getModel('catalog/product_media_config')->getMediaUrl( $_product->getSmallImage());

答案 0 :(得分：2)
在前端，由于速度提高，所有产品图像都来自缓存。
在后端，Magento不考虑速度，因此它来自真实的图像路径。
你不能在方法之外编写任何代码，因为Magento是完全面向对象的。
您可以使用以下代码获取图片完整网址。
echo $imageUrl = Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA) . 'catalog/product' . $_product->getImage();
