eps 图像不会显示

Question

我有一张图，其中每幅图像都显示视频的一帧，因此它们的顺序很重要。我在同一个文件夹中有 eps 文件，并且没有出现任何错误，但是当我运行它时，图像没有显示，而是显示表格单元格，并且文件的名称写在框中。我该如何解决这个问题？

\begin{figure}
\centering
\subfloat{\includegraphics[width = 1in]{S001}\includegraphics[width = 1in]{S002}\includegraphics[width = 1in]{S003}\includegraphics[width = 1in]{S004}} \\
\includegraphics[width = 1in]{S005}\includegraphics[width = 1in]{S006}\includegraphics[width = 1in]{S007}\includegraphics[width = 1in]{S008} \\
\includegraphics[width = 1in]{S009}\includegraphics[width = 1in]{S010}\includegraphics[width = 1in]{S011}\includegraphics[width = 1in]{S012} \\
\includegraphics[width = 1in]{S013}\includegraphics[width = 1in]{S014}\includegraphics[width = 1in]{S015}\includegraphics[width = 1in]{S016} \\
\includegraphics[width = 1in]{S017}\includegraphics[width = 1in]{S018}\includegraphics[width = 1in]{S019}\includegraphics[width = 1in]{S020}
