我也遇到了同样的问题，但我没有使用Nextgen（在我看来这太过火了），而是将Gallerific集成为WordPress gallery的短代码替代品。它工作得非常好，对最终用户来说非常简单，因为他们只需将图像添加到帖子中，然后单击“插入图库”。
我将在下面提供用作参考的代码：
最后，我使用了标题，而不是图像上的描述。
插件：
注意：这使用了Tadlock的Cleaner Gallery插件中的一些逻辑和代码。

Galleric设置
注意：如果您将设置放在一个单独的文件中，并使用wp_enqueue_脚本调用它，将使模板更干净。

我曾计划将其作为插件发布，但它仍需要一些工作才能使我们对大众有用。
