图形环境无法正常工作

图形环境无法正常工作

我试图通过在同一列中并排放置两个图形（一个较长，一个较平）来节省海报上的空间。我在网上读到的所有内容都说要使用图形环境，但由于某种原因，当我使用它时，图像不会出现。我还想在图形的底部添加标签（就像现在一样）。下面是 MWE。现在，中心环境将图像放在单独的空间中，我希望它们并排放置。我不明白为什么图形环境在这个海报文档中不起作用，在常规文件中似乎没有问题。

像这样吗？

并排显示在一列中的图片

\documentclass[a0,landscape]{a0poster}

\usepackage{multicol} % This is so we can have multiple columns of text 
                      % side-by-side
\setlength{\columnsep}{100pt} % This is the amount of white space between the 
                              % columns in the poster
\setlength{\columnseprule}{3pt} % This is the thickness of the black line 
                                % between the columns in the poster
\usepackage{graphicx} % Required for including images
\usepackage[font=small,labelfont=bf]{caption} % Required for specifying 
                                              % captions to tables and figures

\begin{document}

\begin{multicols}{2}% you must specify the number of columns!

\begin{center}% centre whole block
  \begin{minipage}{.5\linewidth}% left side
    \centering% centre within block
    \includegraphics[width=85mm]{example-image-a}% standard image
    \captionof{figure}{caption1}
  \end{minipage}%
  \begin{minipage}{.5\linewidth}% right side
    \centering
    \includegraphics[width=75mm]{example-image-b}
    \captionof{figure}{caption2}
  \end{minipage}%
\end{center}

\end{multicols}

\end{document}
