Howdy,

If I use

	\documentclass{article}
	\usepackage{graphicx}
	\listfiles
	\pagestyle{empty}
	
	\begin{document}
	
	  \noindent\fontsize{15.625mm}{15pt}\selectfont monks\\
	  \fontsize{4mm}{15pt}\selectfont the transatlantic feedback
	
	  \includegraphics[height=16mm]{playloud.jpg}
	
	\end{document}

compiling with pdflatex and xelatex (using xdvipdfmx) seem to give  
exactly the same result.

Good Luck,
