outline image over entire page width

Question

I am probably not the first to ask this question but I have tried every answer I could find before asking it here. The problem is that I want an image (eps) be on the top of the page.

I want to add a header on the top of the page starting at an inch from the top and starting at the side of the page (no margin). I have tried \noindent , raisebox & makebox, outlining it to the left.... All the answers I could find.

However, I keep getting this. I want it to be higher and starting from the left side of the paper.

Code:

\documentclass[11pt]{article}
\usepackage{graphicx} 
\usepackage[a4paper]{geometry}  
\usepackage{epstopdf}
\begin{document}
\begin{titlepage}
\begin{center}
\raisebox{100pt}{\includegraphics[width=\paperwidth]{figures/eb.eps}}
\end{center}
\end{titlepage}
\end{document}

Thank you in advance!

Answer 2

With tikz

\documentclass{article}
\usepackage{tikz}



\begin{document}
\tikz[remember picture,overlay]\node[anchor=north,inner sep=0pt,outer sep=0pt] at
       ([yshift=-1in]current page.north) 
                       {\includegraphics[width=\paperwidth,height=0.75in]{example-image-a}};

blub
\end{document}

Adjust yshift, width and height suitable as you need.
