The process of embedding an image or graphic into a LaTeX document can be done in many ways.

Basic Usage
\usepackage{graphicx}
\graphicspath{ { ./images/ } { ./charts/ } { ./tables } }

\includegraphics{foo}
Graphics Options
The most basic tool for embedding an image into a document is \includegraphics. There are a number of options to configure the image.
\includegraphics[scale=2.5]{foo}
\includegraphics[width=5cm, height=5cm]{bar}
\includegraphics[angle=90]{baz}
Figures
To position an image, and to create a table of figures throughout a document, use figures.
Quick Start
\begin{figure}[h]
\includegraphics{foo}
\end{figure}
Positioning Graphics
Figures take a mandatory option, like h in the example above. Valid values and their meanings are:
Option |

Centering a Graphic
To center a graphic, simply use centering inside the figure.
Side-by-Side Graphics
To display two images side-by-side, try:
\begin{figure}
\centering
\begin{subfigure}{.5\textwidth}
\centering
\includegraphics{foo}
\end{subfigure} %
\begin{subfigure}{.5\textwidth}
\centering
\includegraphics{bar}
\end{subfigure}
\end{figure}
Labeling and Captioning a Graphic
To label an image, use \label{my-label}. The standard practice is to use a label composed as prefix:identifier, so that labels of subfigures can be grouped.
To caption an image, use \caption{my-caption}.
