# How to decorate a tikz rectangle with a box on north center part?

I want to make a rectangle like the image in which I could add an image with \includegraphics. I have the following rectangle code:

\begin{tikzpicture}[overlay,remember picture]
\draw [xshift=3mm,line width=7pt,rounded corners=7pt, draw=black]
($(current page.north west) + (15mm,-15mm)$)
rectangle
($(current page.south east) + (-15mm,15mm)$);
\end{tikzpicture}

Use tcolorbox it has all of this and many more. This must be a duplicate but I can't find it. –  percusse Aug 24 '14 at 18:47
I know with tcolorbox has the option, but I don't want to use it, that's why ask this –  hkviktor Aug 24 '14 at 19:26

I am not sure to understand the question

try this

\documentclass[a4paper]{article}

\usepackage{pgf,tikz}
\usetikzlibrary{fit,calc,positioning}

\begin{document}

\begin{tikzpicture}
\draw [xshift=3mm,line width=5pt,rounded corners=5pt, draw=black,fill=white]
($(cadre.north) + (15mm,-5mm)$)
rectangle
($(cadre.north) + (-15mm,5mm)$);
\end{tikzpicture}
\end{document}


\documentclass[a4paper]{article}

\usepackage{pgf,tikz}
\usetikzlibrary{fit,calc,positioning}

\begin{document}

\begin{tikzpicture}[overlay,remember picture]
\draw [xshift=3mm,line width=7pt,rounded corners=7pt, draw=black]
($(current page.north west) + (15mm,-15mm)$)
rectangle
($(current page.south east) + (-15mm,15mm)$);
\node at ($(current page.north) + (0,-15mm)$) [draw,line width=5pt,rounded corners=5pt,]{\includegraphics[width=4cm]{linux-penguin}};
\end{tikzpicture}

\end{document}

Almost, but the image was supposed to be inside the blue rectangle –  hkviktor Aug 24 '14 at 19:25
