</html>我改变了图像源的那些在Imgur，例如：http://i.imgur.com/WJnFiST.png
当我将代码复制到所见即所得编辑器时，它只显示下面的按钮，但不显示 图片。这是为什么？ http://i.imgur.com/WM3Dmu4.jpg?1
更重要的是如何使文本显示在图像的下方，而不是图像内动态地改变它时，图像也随之变化？
谢谢。那么问题的第一部分呢？当我在Stackoverflow上运行代码时，可以看到图像，但是当我在所见即所得编辑器中运行它时，图像不显示，但只显示下面的3个按钮。 – George
@George我认为它被保存为一个.html文件在您的计算机上。尝试直接在Chrome，Firefox和Explorer等浏览器中打开它。如果它在浏览器中正常工作，我不会担心它不能在你的所见即所得模式下工作。 – mcmxl
