将图像添加到章节标题页

Question

以下代码定义了两个新命令，\ChapterImages和\InsertImage，分别允许您设置逗号分隔的图像名称列表和插入下一张图片。使用这些命令，您可以使用以下命令为章节设置图像

\ChapterImages{
    example-image-a,
    example-image-b,
    example-image-c
}

\includegraphics您可以将当前命令替换为，从而将这些图像逐一插入到章节页面中\InsertImage。每次使用该命令时，该\InsertImage命令都会插入列表中的下一张图片，如果没有更多可用图片，则不执行任何操作。

例如，下面是使用以下代码生成的第 3 章的标题页：

以下是更新后的代码：

代码本身并不令人兴奋：将逗号分隔的图像列表放入 LaTeX3 序列中。然后从序列的前面弹出这些文件名，并\includegraphics每次\InsertImage使用时将其赋值。
