eps figures not showing in Beamer/latex [closed]

Question

I realize that I should use latex and not pdflatex to compile my tex file when I have eps figures in it. However, with beamer while making a presentation, my eps figures aren't showing up at all. Strangely all jpeg images are though! I have checked my path and it is correct.

Here is my slide where the eps figure is:

\documentclass{beamer}

\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{eps2pdf}
\usepackage{amsmath}
\usepackage[labelformat=empty]{caption}
\usetheme{CambridgeUS}

\begin{document}





  \frame{
    \frametitle{This is my slide title}


\begin{figure}
 \begin{center}
   \includegraphics[scale=0.25]{/home/user/Research/epsfigure_without_extension}
    \caption{Wavenumber k=1}
 \end{center}
\end{figure}



}

\end{document}
