# Fancyhdr - the header image collides with the body of the content

I am really confused. In the original document , I had a header that collides with the body of the document. Now for preparing the MWE , I removed the unnecessary packages and code segments. I found that the collision has gone. Please help me out. And secondly , I want to reduce the gap in the header and starting of document. I am attaching both the documents. Sorry for the lengthy question but can't help it out.

\chapter{INSTALL BACKTRACK ON AN ANDROID DEVICE}
\chapterauthor*{K.DINESH KUMAR \par II Year B.Tech CSE}
\section{What is Backtrack?}
BackTrack is a distribution designed by Jason Dennis based on the Ubuntu Linux distribution aimed at digital forensics and penetration testing use. BackTrack provides users with easy access to a comprehensive and large collection of security-related tools ranging from port scanners to Security Audit. Support for Live CD and Live USB functionality allows users to boot BackTrack directly from portable media without requiring installation, though permanent installation to hard disk and network is also an option.\par
\section{Security Tools in Backtrack}

BackTrack includes many well known security tools including:
\begin{itemize}
\item Metasploit for integration
\item Wi-Fi drivers supporting monitor mode (rfmon mode) and packet injection
\item Aircrack-ng
\item Gerix Wifi Cracker
\item Kismet
\item Nmap
\item Ophcrack
\item Ettercap
\item Wireshark (formerly known as Ethereal)
\item BeEF (Browser Exploitation Framework)
\item Hydra
\item OWASP Mantra Security Framework, a collection of hacking tools, add-ons and scripts based on FirefoX.
\item Cisco OCS Mass Scanner, a very reliable and fast scanner for Cisco routers with telnet and enabling of a default password.
\end{itemize}

\section{Installing Backtrack on Android Device}
\subsection{Tools Required}
\begin{enumerate}
\item Backtrack 5 ARM.\\
Download Backtrack 5 ARM from Backtrack official site. Backtrack with ARM architecture only on Backtrack 5 version. ARM architecture not available for Backtrack 5 R1, Backtrack 5 R2, and Backtrack 5 R3.
\item Rooted android device \\
Why rooted android device ? Because we need install some application that need Android to be root
\item Busybox, Superuser, Terminal Emulator, and AndroidVNC. \\
You can download search and all of them on Google Play. BusyBox is installer and uninstaller Android program, Superuser is superuser rights manager for Android, Terminal Emulator is Android's built-in Linux command line shell program, and AndroidVNC is a VNC viewer for Android.
\end{enumerate}
\subsection{Installation}
\begin{enumerate}
\item Extract BT5-GNOME-ARM.7z to folder, for example "BT5" folder and then put on device root directory.
\item Open Terminal Emulator on device then go to BT5 folder using the command \verb+ cd sdcard/BT5 +
\item Then run this following command \verb+ su + and \verb+ sh bootbt + and you will see \verb+ root@localhost +
\item Now lets run Backtrack GUI with VNC viewer \verb+startvnc+
\item To connect wth VNC we must know the port where VNC listening. Run \verb+netstat -anpt+ and remember the port where VNC listening. In this case the port is 59016. Open AndroidVNC and fill the form like this: \\
Nickname : BT5\\
Port     : 5901 \\
\item Connect it and you will see Backtrack 5 interface \par
\textit{Remember! Some of the Backtrack tools can't work properly and do it for your own risk. I hope you can Install Backtrack on Android device without any problems, tell me if you get problems.}
\end{enumerate}
\end{document}


The outputs:

As we prefer only one question per post, I will answer only one for now.

Choice 1:

You can reduce the space between your chapter heading and the pictures by modifying

\newcommand{\mychapter}[1]{
\chapter{#1}
\put(80,700){\includegraphics[scale=.85]{border}}
}}


Simply change (80,700) to (98,670).

\newcommand{\mychapter}[1]{
\chapter{#1}
\put(80,670){\includegraphics[scale=.85]{border}}
}}


Change these dimensions accordingly.

Choice 2:

Another option is to redefine the chapter page style and include a header with the image instead of adding it yourself using \AddToShipoutPicture*.
