在准备 MWE 时，包含某种图形图像通常很有用。在简单情况下，可以通过以下方式完成
\begin{figure}
\centering
THIS IS AN IMAGE
\caption{An image}
\end{figure}
但有时，更能引起共鸣的图像或不封闭在环境中的图像会很有用。通常有一些图像可用于此类目的，特别是由mwe和各种tikz...软件包提供的图像。还有一个来自pstricks。还有其他的吗？
以下是其中一些的简短示例。

有一次我感觉我脑海中浮现出一只青蛙的形象，但它似乎已经淡入背景中。我错过了什么？
答案1
您可以包含默认输入路径中的任何图像。如果您为了明确起见限制为 PNG 文件，
$ grep '\.png' /usr/local/texlive/2020/texmf-dist/ls-R | wc -l
1437
这里太多了，无法一一列出。还有一些会在文档树中
如果你限制到 tex 树，那么
$ find /usr/local/texlive/2020/texmf-dist/tex -name '*.png' | wc -l
76
或完整列表
find /usr/local/texlive/2020/texmf-dist/tex -name '*.png' | sed -e 's@.*/@@'
