Include graphics in LaTeX

Question

I am newbie to LaTeX and I have a simple problem including graphics to the text. When I run

\documentclass[10pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\begin{document}
\begin{figure}
\begin{center}
\includegraphics[width=0.25cm,height=0.25cm]{Figure1}
\caption[Sèries temporals de vent i direccions]{Sèries temporals velocitat de vent       direccions. filtratge de pics i glaçades de velocitat.}
\label{Serie}
\end{center}

\end{figure}
\end{document}

I create a pdf file but there is no figure inserted. The picture is called Figure1.png but it seems that the program do not recognizes it and doesn't inserts it. I would appreciate some help.

Answer 1

You are not getting any error at all!. Interesting. This naswer is based on a pure guess. Basically your problem is perhaps the dimensions of the figure you are using in \includegraphics[width=0.25cm,height=0.25cm]{Figure1}. The length 0.25cm itself is a small dimension and depending on your figure (like the white space it may have around etc.), your figure may not be visible at all. If you magnify say, 400 times you may be able to see something.

As such your figure dimensions are looking like this:

The black box is your figure.

Now try with these dimesions:

\includegraphics[width=10cm,height=10cm,keepaspectratio]{Figure1}

This is the dimension you should see:

The above assumes that your figure file is in the same folder as your tex file. Also, as mentioned in comments, put \centering instead of \begin{center}... to avoid extra (unnecessary) vertical space.

If your problem is still not solved, additional details may be necessary for diagnosis. (If you provide your figure file Figure1.png, it might have been better.)
