如何全局设置图片与下方文字间距

@u7751 这个图都没上传成功...

另外你可以看一下mwe宏包提供的example-image.pdf图片。

反对一下@u79794 老师的观点

caption宏包提供的\abovecaptionskip与\belowcaptionskip只能调节caption与图片之间的距离

而要想调节浮动体(float)与文本(text)之间的距离，可以调整以下参数：

• \textfloatsep — distance between floats on the top or the bottom and the text;
• \floatsep — distance between two floats;
• \intextsep —— distance between floats inserted inside the page text (using h) and the text proper.

在你的例子中，可以调整\intextsep的长度

\documentclass{article}
\usepackage[font=small]{caption}
\usepackage{lipsum}
\usepackage{graphicx}
\begin{document}
\setlength{\intextsep}{.2\baselineskip} 
% change the distance between the caption and the bottom of the images
% \setlength\abovecaptionskip{.2\baselineskip}
% change the distance between the float and next text
\lipsum[1-2]
\begin{figure}[htbp]
    \centering
    \begin{minipage}{.49\linewidth}
        \centering
        \includegraphics[width=.99\linewidth]{example-image}
        \caption{A}
    \end{minipage}
    \begin{minipage}{.49\linewidth}
        \centering
        \includegraphics[width=.99\linewidth]{example-image}
        \caption{B}
    \end{minipage}
\end{figure}
\lipsum[3]
\end{document}
