# title page in the same page with other elements

I created a title page with command:

\title
\author


but when I add in the page of the title some elements another page is created and the title is in that new page created. How can I join title and other element such as figures in only one page?

\begin{titlepage}

\includegraphics[width=0.25\textwidth]{Immagini/unict}

\title{Scelta di un progetto di investimento}
\author{Vincenzo Pomona \\  Salvatore Mazzarino}
\maketitle

\end{titlepage}


Edit

My document class is book

\maketitle makes an additional title page; creating its own titlepage environment. Just remove your \maketitle.
The idea is either to a) create an automated title page with \author, \title, etc. and \titlepage, OR b) create a hand-made title page with \begin{titlepage}...\end{titlepage}.
If you delete \maketitle and make your own title page, don't forget to fill in \title and \author in the preamble of your document (before \begin{document}, since the class file will probably use this information for headers and things like that.
