推荐答案

首先要找出浏览器的原因无法加载图片。



大多数现代浏览器都有开发者工具，按F12即可访问。



这些工具具有网络跟踪。这将显示页面尝试加载的所有服务器资源。



查找图像并检查http状态代码。这个状态代码将是您的线索。

First thing is to find out why the browser can't load the image.

Most modern browsers have developer tools which can be access by pressing F12.

These tools have a network trace. This will show all the server resources the page tries to load.

Look for the image and check the http status code. This status code will be your clue.
