image inclusion does not work properly

[GoogleCodeExporter]

What steps will reproduce the problem?
I am attempting to include an image as part of the file using the follwoing:
\begin{figure}[h]
\begin{center}
\includegraphics[width=\columnwidth]{DATAFLOW.pdf}
    \end{center}
    \caption{Data Flow}
\label{DataFlow}
\end{figure}

What is the expected output? What do you see instead?

I expect to see the image, but a blank space occurs instead. 

What version of the product are you using? On what browser?

I've tried Chrome and mozilla using the preview release
Please provide any additional information below.

                                            \centering
                                            \includegraphics{DataFlow.jpg}
                                            \caption{g}
                                            \label{sd}
                                            \end{figure}

Have you added the file to Project Resources? If not, go to Project > Project 
Resources, check the image file(s) you want to include, and hit "okay". If the 
image changes, go to Project > Refresh Project Resources. You may need to 
re-add the resources every time you re-open Latex Lab, but maybe not. Note that 
this is in addition to doing the "includegraphics{}" thing.

I'm running into the same problem, and have added the .pdf as a resource.  The 
TeX output states that the image file isn't found.
