how to include graphics in pdf output

["Christopher W. Ryan" <cryan@binghamton.edu>]

I am running org mode 7.7 on Win XP. I hope to export a document to pdf,
and I'd like to include an image in it. The image is a file called
DataLoggerImage.jpg; it resides in the same directory as my org file.

These are the first three lines of my org file:

#+OPTIONS:   todo:nil toc:nil tags:nil
#+LATEX_HEADER: \usepackage[margin=1in]{geometry}
#+LATEX_HEADER: \usepackage{graphicx}


I have tried the following code to include a figure (tried both
approaches simultaneously, and the second one alone, neither with success):

\begin{figure}\centering
\includegraphics{DataLoggerImage}
\caption{Temperature and humidity data logger}\label{datalogger}
\end{figure}

#+CAPTION: Temperature and humidity data logger
#+LABEL:   datalogger
[[./DataLoggerImage.jpg]]

The figure does not appear in the resulting pdf.  Any advice as to what
I am doing wrong?

Thanks.
