I am trying to add a custom header to a pdf via markdown. This page has been very helpfull. My working solution is below.
\addtolength{\headheight}{1cm}
\fancypagestyle{plain}{}
\rhead{\center\includegraphics[height=3cm]{path}}
\renewcommand{\headrulewidth}{0pt}
While this provides the desired solution on the title page with the correctly sized logo and space between the header and the text, there is extra blank space on the following pages. How can I remove (or control) the header spacing on pages > 1?
