I have a \begin{multicols}{2} document with these conditions.
\documentclass[12pt]{article}
\usepackage[lmargin=2cm, rmargin=2cm, top=1.5cm, bottom=2cm]{geometry}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[british,UKenglish,USenglish,english,american]{babel}
However I can't find a way of inserting an image inside one of the columns, like in the image.
So far I've tried these two options:
\begin{figure}
% \centering
\includegraphics[width=.30\linewidth]{images/GRIN1.png}
\caption{Subunidad de NMDA codificada por GRIN1. Imagen obtenida con \textit{Chimera}.}
\label{fig: GRIN1}
\end{figure}
\bigskip
\noindent
\begin{minipage}{\linewidth}
\centering
\includegraphics[width=.30\linewidth]{images/GRIN1.png}
\captionof{Subunidad de NMDA codificada por GRIN1. Imagen obtenida con \textit{Chimera}.}{Figure caption}
\label{fig:cc}
\end{minipage}
But the first one seems to be ignore by latex, and the second one gives me different errors.


multicolsenvironment you can not insert floats. – Zarko Jul 11 '21 at 18:00
