如何在每一页的四个角落使用一张图片？

Question

我想在每一页的四个角使用一张图片，其中一个角有此代码

\backgroundsetup{%
scale=1,
angle=0,
contents={\includegraphics[width=5cm]{example.jpg}},
position=current page.north east,
anchor=below left,
}

但是有了这个，我只能在右上角放置一张图片，我找不到放置在其他角落的说明，所以我需要帮助。

谢谢

受到此链接的启发：将图像报告放在每一页的绝对位置一个解决方案就是这个

\documentclass{article}
\usepackage{background}
\usepackage{graphicx}
\usepackage{lipsum}

\backgroundsetup{
    scale=1,
    angle=0,
    opacity=1,
    color=black,
    contents={\begin{tikzpicture}[remember picture, overlay]
            \node at ([xshift=-2cm,yshift=-2cm] current page.north east)
            {\includegraphics[width = 2cm]{lion.png}} %
            node at ([xshift=2cm,yshift=-2cm] current page.north west)
            {\includegraphics[width = 2cm]{lion.png}}% 
            node at ([xshift=-2cm,yshift=2cm] current page.south east)
            {\includegraphics[width = 2cm]{lion.png}}%
            node at ([xshift=2cm,yshift=2cm] current page.south west)
            {\includegraphics[width = 2cm]{lion.png}};
    \end{tikzpicture}}
}
\begin{document}
    
    \lipsum[1-7]
    
\end{document}

结果：
