How to insert an image at the top center of the first page?

Question

I would like to insert a logo in the top center of the first page, before the title and the authors name. If I use the command \begin{figure} it turns out another new page before the title with the image. I have also tried not to use \begin{figure}. The main text code is below:

Answer 1

I relented and produced a very cut down version of your MWE and placed a graphic above your title.

% logoprob.tex  SE 637240
%\documentclass[5p,sort&compress]{elsarticle}
\documentclass[final,5p,times,twocolumn,authoryear]{elsarticle}
\usepackage{graphicx}
\usepackage{mwe}   %%%% PW added for the image
\begin{document}
\begin{frontmatter}
%\centering\includegraphics[width = .8\linewidth]{img/logo-polimi_600x250.png}
\title{{\begin{center}\includegraphics{example-image-a}\end{center}}
    \vspace{1cm}Laboratory experiment 1: Magnetic Nanoparticles}
\author{A. N. Author}
\address{Somewhere}
\begin{abstract}
text 
\end{abstract}
\end{frontmatter}
\end{document}

Answer 2

I removed all packages and other commands except for the section \makeatletter\def\ps@pprintTitle (it removes the Preprint submitted to Elsevier).

The lazy solution I applied was to insert \centering\includegraphics[width=0.3\linewidth]{example-image-1x1}\\ inside the definition of title. Not the most elegant solution, but a simple one. I replaced your figure for one from the standard installation example-image.

I also added the package lipsum to better visualize the contents from abstract and sections.

Suggestions for creating your own customized title page:

• How to customize my titlepage?
• Use the values of \title, \author and \date on a custom title page
• https://pt.overleaf.com/learn/latex/How_to_Write_a_Thesis_in_LaTeX_(Part_5)%3A_Customising_Your_Title_Page_and_Abstract

A MWE follows:

\documentclass[final,5p,times,twocolumn,authoryear]{elsarticle}
\usepackage{lipsum}
\title{\centering
  \includegraphics[width=0.3\linewidth]{example-image-1x1}\
  Laboratory experiment 1:\
  Magnetic Nanoparticles}
\author{Author}
\address{Address}
\makeatletter
\def\ps@pprintTitle{%
  \let@oddhead@empty
  \let@evenhead@empty
  \def@oddfoot{\footnotesize\itshape
    \hfill\today}%
  \let@evenfoot@oddfoot}
\makeatother
\begin{document}
\begin{frontmatter}
  \begin{abstract}
    \lipsum[65-68]
  \end{abstract}
\end{frontmatter}
\section{First section}
\lipsum[66-67]
\end{document}
