Your code looks fine. Problem seems with the image's path. Try setting it to fully qualified path to images and it will work for you.

你的代码看起来很好。问题似乎与图像的路径有关。尝试将其设置为图像的完全限定路径，它将适合您。

Also if you are manipulating HTML from the server side code. Then I'll suggest you to map image paths using Server.MapPath(). and it will work fine.

此外，如果您从服务器端代码操作HTML。然后我建议你使用Server.MapPath（）映射图像路径。它会工作正常。
