Answer by Zarko for breaking one column in two column article

• your question is not very clear. do my suspect, that you have standard two column document and you like to have figure over two columns on the same page where it is insert in text?
• if my guessing s correct, than you can this achieve with package stfloats
• off-topic: newer put floats environments inside \begin{center}...\end{center} or any other no float environment.

\documentclass[twocolumn]{article}\usepackage[english]{babel}\usepackage{lipsum}\usepackage{times}\usepackage{graphicx}\usepackage{stfloats} % for positioning of figure* on the same page\begin{document}\thispagestyle{empty}\lipsum*[1]    \begin{figure*}[b]\centering\includegraphics[height=10cm]{example-image-b}    \end{figure*}\lipsum[2-4]\end{document}
