Align images in institute in tikzposter

Question

I would like to align three figures by their center inside the institute command in tikzposter.

In beamer, I would use columns but it is not possible to do so inside institute. Currently I'm just importing the figures using includegraphics and spacing them with hspace.

MWE:

\documentclass{tikzposter}

\usepackage{mwe}

\title{Poster Title}

\author{Author} 

\institute{
    \includegraphics{example-image-a}
    \hfill
    \includegraphics{example-image-b}
    \hfill
    \includegraphics{example-image-c}
}

\begin{document}
    \maketitle
\end{document}

Answer 1

You can define a command \midlinegraphic that takes 2 arguments: the graphic height and filename, which then uses \raisebox to shift the graphic down by half that height.

MWE

\documentclass[demo]{tikzposter}
\newcommand{\midlinegraphic}[2]{%
  \raisebox{-#1/2}{\includegraphics[height=#1]{#2}}}
\institute{
  \midlinegraphic{1cm}{A}
  \midlinegraphic{3cm}{A}
  \midlinegraphic{2cm}{A}
}
\begin{document}
\maketitle
\end{document}
