\section{Picture}

The following picture (\ref{fig:a-field}) depicts a yellow field with a tree and spans over the entire line width:

% Wrapfigure

\section{Wrap text around figure}

\begin{wrapfigure}{l}{0.5\linewidth}
    \centering
    \noindent
    \includegraphics[width=\ScaleIfNeeded]{res/adam.jpg}
    \caption{Adam Cole}
    \label{fig:some-adam}
\end{wrapfigure}
It may be noted that the width of the image included was specified relative to width of the text.
It is a good idea to use relative sizes to define lengths, particularly when using wrapfigure.
In the example above, the figure covers exactly half of the the textwidth, and the actual image uses a slightly smaller width, so that there is a pleasing small white frame between the image and the text. The image should always be smaller (less wide) than the wrap, or it will overrun the text.
Take care while using adding wrapfigures very near the top or bottom of a page, as this can often cause unwanted effects that are hard or near-impossible to solve. It is not advisable to try to use wrapfigures alongside equations or sectional headers. They also cannot be used in lists, such as itemize and enumerate environments.
