Putting graphics in latex

[cdhotfire]

Can someone help me, I put
\begin{figure}[h]
\centering
\includegraphics{C:/Math.png}
\end{figure}

I even tried to do this with .eps, but it still keeps saying that its an undefined control sequence.

Do you have the correct \usepackage{} command at the top of your source file?
