我一直在通过youtube上的Dave Jones教程学习Ruby on Rails 4，但在第4课上我遇到了一个小障碍。从FreeHTML5模板导入模板时。。。当我将第一个顶部照片cowboyup.jpg从img标记更改为rails标记时，它可以工作，但底部的4个照片标记（ad125.jpg）不能工作。当我进入firefox进行测试时。我带着萤火虫来查看来源。img标签在源代码中，但firebug通知我无法加载图像。

这是到目前为止我的代码。

您的

图像

是否位于

资产/图像

右侧？对于第一张照片，您在名称前加上路径前缀。最后两个似乎忽略了这一点。虽然只有当它们不在资产/图像中时才有必要这样做，但我已经解决了问题。显然，adblock plus不喜欢文件名ad125.jpg。当我更改文件名时，照片出现了。事实证明这很有趣。
