# Aligning multiple authors (with pictures) in a grid

Working on a project with 4 members, I'd like to align the authors in an "even" way on the title page. I'm thinking a simple 2 by 2 "grid" would likely look best, but I'm having some issues getting it to work.

The current code gives me the three first authors on one line, with the fourth on a separate line.

The titling package seems like it could be used for what I want by encasing the author part in some kind of table, but even just including it gives me the error Argument of \reserved@a has an extra }. As far as I can tell, this error is because of there being images within the \author command (Note that due to a requirement of this particular assignment, the images are needed).

Any help would be appreciated!

\documentclass[11pt, titlepage, a4paper]{article}
\usepackage{graphicx}

\begin{document}
\title{Project report}
\author{A. Uthor \\YYMMDD-XXXX \\ \includegraphics{photo}
\and A. Uthor \\YYMMDD-XXXX \\ \includegraphics{photo}
\and A. Uthor \\YYMMDD-XXXX \\ \includegraphics{photo}
\and A. Uthor \\YYMMDD-XXXX \\ \includegraphics{photo} }
\maketitle
\end{document}

Set the authors in a nested tabular to arrange them properly:

\documentclass[11pt, titlepage, a4paper]{article}
\usepackage{graphicx}% http://ctan.org/pkg/graphicx
\newcommand{\authorblock}[1]{\begin{tabular}{@{}c@{}}#1\end{tabular}}
\title{Project report}
