[Tex/LaTex] Add logos to the right and left of the title of the poster (tikzposter)

Question

I want to add logos to the top corners of my poster.
This is what I have:

    \author{\textsuperscript{1}Joshua R.~Palmer \& 
    \textsuperscript{2}Gabriel Taylor}    
    \institute{\textsuperscript{1}The University of Texas Rio Grande Valley 
               \& \textsuperscript{2}University of Wisconsin - Madison} 
  \titlegraphic{\includegraphics[width=0.2\textwidth]{coe.jpg}}

\begin{document}   
\maketitle
\centering
\begin{columns}
    \column{0.34}

This is what I want:

Answer 1

A perhaps slightly hackish method, that will work regardless of theme, but that requires a bit of trial and error, is to simply use a couple of \nodes to place the images. A tikzposter is just one big tikzpicture, and the coordinates bottomleft and topright are defined by the class, so you can do something like this:

\documentclass[a2paper]{tikzposter}
\usetikzlibrary{positioning}
\begin{document}   
\maketitle
\node [below right=4cm and 2cm] at (bottomleft |- topright) {\includegraphics[width=4cm]{example-image-a}};
\node [below left=4cm and 2cm] at (topright) {\includegraphics[width=4cm]{example-image-b}};
\end{document}

The distances in e.g. below right=4cm and 2cm has to be modified depending on the papersize used, the position of the title, and what you like yourself. The first length is the vertical distance, the second the horizontal.
