快速、粗糙且不太完美:
\documentclass{article}
\usepackage{graphicx}
\usepackage{subcaption}
\begin{document}
\begin{figure}
\raggedleft
\rotatebox[origin=c]{90}{Some text}
\fbox{%
\begin{minipage}{0.9\linewidth}
\includegraphics[width=2cm,height=4cm]{example-image}\hfill
\includegraphics[width=2cm,height=4cm]{example-image}\hfill
\includegraphics[width=2cm,height=4cm]{example-image}\hfill
\includegraphics[width=2cm,height=4cm]{example-image}\hfill
\includegraphics[width=2cm,height=4cm]{example-image}
\end{minipage}%
}
\rotatebox[origin=c]{90}{Some other text}
\fbox{%
\begin{minipage}{0.9\linewidth}
\includegraphics[width=2cm,height=4cm]{example-image-a}\hfill
\includegraphics[width=2cm,height=4cm]{example-image-a}\hfill
\includegraphics[width=2cm,height=4cm]{example-image-a}\hfill
\includegraphics[width=2cm,height=4cm]{example-image-a}\hfill
\includegraphics[width=2cm,height=4cm]{example-image-a}
\end{minipage}%
}
\rotatebox[origin=c]{90}{Some third text}
\fbox{%
\begin{minipage}{0.9\linewidth}
