[Tex/LaTex] png not scalable LaTeX using TexShop on Mac

graphicspdftexpng

After searching for a long time unfortunately I couldn't find a proper answer or used everything I found without any change.

I have several PNG files to include into my thesis but after including a .png image it's not possible to scale it or get it in the right position.

Just a short excerpt from my TeX document:

\documentclass[11pt,a4paper,twoside,openright]{memoir}
\usepackage[ngerman]{babel}
\usepackage[latin1]{inputenc}
\usepackage[dvips]{color}
\usepackage[pdftex]{graphicx}
\usepackage{epstopdf}
\usepackage{epsfig}

\begin{document}
    \section{Motivation}
    \label{sec:motivation}
    Lorem Ipsum ist ein einfacher Demo-Text für die Print- und Schriftindustrie.
    Lorem Ipsum ist in der Industrie bereits der Standard Demo-Text seit 1500,
    als ein unbekannter Schriftsteller eine Hand voll Wörter nahm und diese
    durcheinander warf um ein Musterbuch zu erstellen.

    \begin{figure}[!ht]
       \centering
       \includegraphics[width=\textwidth]{chapter/intro/images/image.png}
       \caption{caption}
       \label{fig:label}
    \end{figure}

\end{document}

And it looks like this:

The image is neither scaled nor on the chosen position.

The LaTeX template above is provided by my university and recommended to use for my thesis. Before using that template I created clean, new document to play around and learn how to use latex.
There I used .png images as well with no problems, I could center it, place it in position and scale it.

This document looks as follows:

\documentclass[12pt,a4paper]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{graphicx}
\usepackage{capt-of}
\usepackage{url}
\usepackage{bibgerm}
\bibliographystyle{alphadin}

\begin{document}
    %
    \begin{figure}
       \centering
       \includegraphics[scale=.3]{image.png}
       \caption{caption}
       \label{fig:label}
    \end{figure}
    %
\end{document}

Now I'll just go on writing and hope to get any help in here because I don't know what to do anymore except creating a totally new document.

At first remove the (conflicting) options dvips and pdftex. Remove also the epsfig package. If the problem persist you will have to put the image on the net for inspection.
