将自动生成的URLAddress is used as the name of the picture, and the picture is added.When customers need to download this picture, they can download it directly without renaming it; If you add a product for the convenience of drawing, simply name the picture as1,2,3的话，客户下载这张图片后还需要重新命名，那么网站的用户体验会有所下降。产品多图的添加也是一样的道理，为了不和上面的主题图片重名，可以选择 “产品编码+Keywords+数字”的命名方式。
