How to order 3 images horizontally?

Question

I use the following code to include three images:

\begin{figure}[h]
\includegraphics{delete_gesture.png}
\caption{Awesome Image}
\label{fig:awesome_image}
\end{figure}

\begin{figure}[h]
\includegraphics{ok_gesture.png}
\caption{Awesome Image}
\label{fig:awesome_image}
\end{figure}

\begin{figure}[h]
\includegraphics{settings_gesture.png}
\caption{Awesome Image}
\label{fig:awesome_image}
\end{figure}

Now the images are ordered vertically. I want them horizontally. I tried to use columns or multicols but couldn't find a solution. Any hint?

Answer 1

put them all together in one figure environment and the three minipages without an empty line

\documentclass[english]{article}
\usepackage[demo]{graphicx}
\usepackage{babel,blindtext}

\begin{document}

\blindtext

\begin{figure}[!htb]
\minipage{0.32\textwidth}
  \includegraphics[width=\linewidth]{delete_gesture.png}
  \caption{A really Awesome Image}\label{fig:awesome_image1}
\endminipage\hfill
\minipage{0.32\textwidth}
  \includegraphics[width=\linewidth]{ok_gesture.png}
  \caption{A really Awesome Image}\label{fig:awesome_image2}
\endminipage\hfill
\minipage{0.32\textwidth}%
  \includegraphics[width=\linewidth]{settings_gesture.png}
  \caption{A really Awesome Image}\label{fig:awesome_image3}
\endminipage
\end{figure}

\blindtext

\end{document}

Answer 2

Here is a solution with subfigure package. It has 2 rows and 2 columns of images. The widths are chosen such that it fits into a column of a 2-column page. I guess you get the idea.

\begin{figure}[t]
\centering
\subfigure[text]{
\includegraphics[width=.225\textwidth]{file}
}
\subfigure[text]{
\includegraphics[width=.225\textwidth]{file}
}

\subfigure[text]{
\includegraphics[width=.225\textwidth]{file}
}
\subfigure[text]{
\includegraphics[width=.225\textwidth]{file}
}

\caption{blablabla}
\label{fig:whatever}
\end{figure}

As you can see it's pretty simple to have to images/objects next to each other -- just put them into the same line. Or you can use multicol inside a figure.

Please note that subfigure is superseded by subfig which provides \subfloat command instead of \subfigure. More compatibility information is found in the subfig documentation.

Answer 3

I use the following technique:

\begin{figure}[h]       
    \fbox{\includegraphics{fig1.pdf}}   
    \hspace{30px}
    \fbox{\includegraphics{fig2.pdf}}
    \hspace{30px}
    \fbox{\includegraphics{fig3.pdf}}
    \caption{this is the caption}
    \label{materialflowChart}
\end{figure}

This places a thin line around each image (as it uses framebox). You can use \mbox in the same way if you don't want a frame. The \hspace{} command is a convenient way of controlling the spacing between the two images.
