I'd like to use tikz to position a graphic at the lower right hand corner of a minipage. I've gotten this far (this isn't quite an MWE, since it depends on a locally available imagefile).
\documentclass{article}
\usepackage{lipsum}%
\usepackage{fullpage}%
\usepackage{tikz}%
\usepackage{graphicx}%
\begin{document}
\begin{minipage}{.5\textwidth}
\begin{tikzpicture}[overlay]
\node{\includegraphics{imagefile}};
\end{tikzpicture}
{\Large\bfseries Title}%
{\em Subtitle}%
\begin{flushleft}
\lipsum[1]
\end{flushleft}
\end{minipage}
\end{document}
That gets me here (with a suitable image for the "7"):
What I'd like, ultimately, is something like this:
tikzmarks
maybe?
