how to insert a gap in a title for pictures in Latex?

I want a gap between the BFH name of course and the picture

I tried to add a {}\\ in between or a \newline but it doesn't work.

Thanks

here is the code

\documentclass[12pt]{report}
\usepackage{url}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\graphicspath{{images/pictures/}} %configuring the graphicx package

\title{\textbf{Assessment and retrofitting}\\
     {\large BFH name of course}\\
     {\includegraphics[width=0.75\textwidth]{images/pictures/global overview 1.jpg}}\\
     %try to create a gap in the picture
}
\begin{document}

\maketitle
\tableofcontents 

You could use the titlepage environment to design the page however you want it:

\documentclass[12pt]{report}
\usepackage{graphicx}

\makeatletter
\newcommand{\subtitle}[1]{\def\@subtitle{#1}}
\makeatother

\title{Assessment and retrofitting}
\subtitle{BFH name of course}
\author{names}

\begin{document}

\makeatletter
\begin{titlepage}
    \centering
    \vfill
    {\bfseries\Large\@title\par}
    \vskip0.5cm
    {\large\@subtitle\par}
    \vskip1cm
    \includegraphics[width=0.75\textwidth]{example-image-duck}
    \vfill
    \@author
    \vfill
    \@date
    \vfill
    \vfill
\end{titlepage}
\makeatother

\end{document}
