I have already seen this and this and this and this.
I have one section of a baposter:
\headerbox{Results - Base Model Performance}{name=performance,column=1,span=2,row=0}{
\begin{multicols}{2}
Text here about base model performance. This is the entire column.
\begin{center}
\includegraphics[scale=0.5]{Fig3b}
\end{center}
\end{multicols}
I cannot use a \figure inside a the multicols environment, because I get a compilation error. Originally, I had:
\begin{figure}\flushleft
\includegraphics[scale=0.5]{Fig3b}
\end{figure}
But of course that wouldn't compile.
How can I align the figure to the left of the column?
