Background image (Logo) gets hidden when I put another image

backgroundsbeamerfloatslogos

I am making a latex beamer presentation. The blank slide (with logo of a lion in background) looks like as shown Fig

Now, I want to add an image of a figure to this slide. When I add the figure to slide, the background logo gets hidden as shown in the second Figure here enter image description here

However, I do not want to hide the background logo of tiger. The background logo should also be completely visible along with the image. Please guide me for a possible solution.

The code is given as follows:

 \documentclass[compress, xcolor=table]{beamer}
\usebackgroundtemplate{\includegraphics [width=\paperwidth,height=\paperheight]{slide_bg.png}}
    \begin{document}
        \section{Model order reduction of commensurate fractional order systems}
        \subsection{Proposed approach}
        \begin{frame}[t]{\bigskip \Large \vspace{-5mm}Model order reduction of commensurate fractional order systems }
            \textbf{Proposed approach}
            \begin{figure}[![enter image description here][3]][3]
            \begin{center}
                \includegraphics[height=4.4cm]{LFC121.jpg}
                \vspace{6mm}
                \caption{Block diagram of single area power system with controller}
            \end{center}
            \end{figure}
        \end{frame} 
    \end{document}

Also, the figures used in the above code are also attached below

The problem seems to be that you are using a jpg file, which cannot be transparent and hence cover the background image.

Your code works fine as it is, provided the image in the figure is transparent (typically, a png file):

 \documentclass[compress, xcolor=table]{beamer}
\usebackgroundtemplate{\includegraphics [width=\paperwidth,height=\paperheight]{example-image}} % Courtesy of mwe package
    \begin{document}
        \section{Model order reduction of commensurate fractional order systems}
        \subsection{Proposed approach}
        \begin{frame}[t]{\bigskip \Large \vspace{-5mm}Model order reduction of commensurate fractional order systems }
            \textbf{Proposed approach}
            \begin{figure}[![enter image description here][3]][3]
            \begin{center}

                \caption{Block diagram of single area power system with controller}
            \end{center}
            \end{figure}
        \end{frame} 
    \end{document}

(You need to download this file and place it in the same folder as your source code for this example to compile).

Simply add transparency to your file: you can use gimp to do that, or you can look for solutions on-line.
