Caption
It is usually beneficial to include caption to your images. To do so, simply use the command \caption{'text'} either below or above your figure (usually below for images and above for tables).
\begin{figure}[]
\centering
\includegraphics[width=0.5\textwidth]{CylinderImage.jpg}
\caption{Caption written below figure.}
\end{figure}
\begin{figure}[]
\centering
\caption{Caption written above figure.}
\includegraphics[width=0.5\textwidth]{CylinderImage.jpg}
\end{figure}
Figure Environment
The most comman method to included images is using the Figure environment.
\begin{figure}[placement specifier]
... figure contents ...
\end{figure}
Placement specifiers
The placement specifiers available when inserting figures are as shown in the table below. This table is taken from LaTeX Floats, Figures and Captions, so check it out for more detailed information.
| Specifier | Permission |
|---|---|
h | Place the float here, i.e., approximately at the same point it occurs in the source text (however, not exactly at the spot) |
t | Position at the top of the page. |
b | Position at the bottom of the page. |
p | Put on a special page for floats only. |
! | Override internal parameters LaTeX uses for determining "good" float positions. |
H | Places the float at precisely the location in the LaTeX code. Requires the float package, i.e., \usepackage{float} |
It is also common to use the command \centering to center the image on the page. For example:
\begin{figure}[]
\centering
\includegraphics[width=0.5\textwidth]{CylinderImage.jpg}
\end{figure}
