以编程方式随机将图像放置在文本周围

Question

在 MWE 中：

\documentclass[table]{standalone}
\usepackage{lipsum, graphicx, polyglossia, enumitem, amssymb, pifont, booktabs, cancel, animate, ulem, ragged2e}
\usepackage[most]{tcolorbox}
\graphicspath{ {/home/sandip/Downloads/} {images/} }
\linespread{2}

\newtcolorbox{highlightbox}{%
  enhanced,
  colframe=black,
  boxrule=2mm,
  coltext=white,
  colback=black}

\newtcolorbox{mybox}[2][]{%
  enhanced,
  before upper=\setlength{\parskip}{\bigskipamount},
  colframe=black,
  boxrule=2mm,
  bottomrule=8mm,
  colbacktitle=black,
  fonttitle=\bfseries\centering,
  coltitle=white,
  colback=yellow!10!white,
  coltext=black,
  watermark zoom=1,
  watermark color=black,
  watermark opacity=.05,
  clip watermark,
  watermark text={\rotatebox{65}{Watermark}},
  title=#2,#1}

\newcommand{\xxbody}{
  \lipsum[2,4]
}

\newcommand{\xxheading}{%
  Heading
}

\begin{document}

\begin{mybox}{\LARGE \xxheading{}}

  \xxbody{}

\end{mybox}

\end{document}

在文件夹 ./images 中，我有几个图像文件。

我想将它们全部随机放置在文本周围并进行随机旋转。但同时，我又不希望它们杂乱地挤在一起。

这些图像都是微小的图标，将它们随机放置在文本周围可以提高文档的视觉吸引力，至少在我看来是这样:)

我怎么做？

问题这里和这里有类似的东西。但没有涉及文本。

Answer 1

以下将每页最多 10 张图片（数量随机）放置在随机位置。图片是从有效图片列表中随机抽取的。

新代码

放置在边缘的任意位置，没有碰撞保护（但根据图像的大小，可能性很小，只需更改种子）。
