Graphics, Figures & Tables ⇒ Images not appearing

[Dag9]

Hi everyone, I'm very new to LaTeX since I just started writing my dissertation with it, and while I was able to overcome most problems by looking in forums such as this one, I can't find any straightforward solution to this particular issue, so here I am
I started from a template that my university provided, but the images for some reason do not appear in the final pdf. They seem to be there, because if for example I change their size the blank space in which they should be also changes in size, but there's just a void. Here's the frontispiece code as an example:

Code: Select all

\documentclass[11pt,a4paper,twoside,openright]{book}

\usepackage[dvips]{graphicx}
\usepackage{tabularx}
\usepackage{subfigure}
\usepackage{afterpage}
\usepackage{amsmath,amssymb}            
\usepackage{rotating}  
\usepackage{fancyhdr}  
\usepackage[scriptsize]{caption} 
\hyphenation{a-gen-tiz-za-zio-ne}

\setlength{\paperwidth}{16cm}
\setlength{\paperheight}{24cm}
\setlength{\oddsidemargin} {2. cm}
\setlength{\evensidemargin} {2. cm}
\addtolength{\oddsidemargin} {-0.4 cm}
\addtolength{\evensidemargin} {-0.4 cm}
\linespread{1.1}

\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\renewcommand{\captionfont}{\normalfont \sffamily \itshape \small}

\pagestyle{empty}

\begin{document}
	
\thispagestyle{empty}
\vspace*{-1.5cm} \bfseries{
	\begin{center}

		\end{figure}
	\vspace*{0.3cm} \LARGE
	\textbf{TITLE}\\
	\end{center}

\end{document}

A few more things that may or may not be related to the issue, according to my Google searches:
I'm using MikTeX with TeXstudio and PdfLaTeX as default compiler (and, if I switch to XeLaTeX I can actually see the images, but the page layout gets completely distroyed and a few errors arise, so I'd like to stick to PdfLaTeX if possible). The images are all .png and in the same folder as the .tex, and I can even see the preview in the GUI.

A hundred thanks to anyone who'd help me out, I'm getting kind of desperate

The template is full of avoid this code. You should at least remove option dvips. And the figure environment doesn't make any sense on a title page. But there a lot of other things, you should never do. So I would recommend not to use such a broken template but begin from scratch with an introduction to LaTeX.

A note on how to create a title page.

Yeah, somehow I imagined that was the case, I just didn't want to believe it haha
I guess I'll start over, thank you both!
