[Tex/LaTex] Inserting figures using loops

Question

I have a set of pictures in my working directory and I want to make a PDF report using these images. I want to include all of them, but the number of the pictures changes in each case. I would like to make a "for" loop to insert each picture one after the other sequentially. Can anyone help me?
At the moment the code I have is the following:

\begin{figure}[h!]
\begin{centering}
\includegraphics[width=10cm,height=10cm]{Figure1.png}
\caption[Sèries temporals de vent i direccions]{Sèries temporals velocitat de vent i     direccions. filtratge de pics i glaçades de velocitat.}
\label{Serie}
\end{centering}

\end{figure}

I would like to do it for every .png image in the directory.
Thanks for your questions: I am using Windows 7 and the file names follow the pattern Figura1.png, Figura2.png and so forth. So which of these possibilities would fit best?

Answer 1

Suppose your pictures are all following certain naming convention (here I used pic1.png up to pic4.png), the lipsumpackage is just for the dummy text:

\documentclass[parskip]{scrartcl}
\usepackage[margin=10mm,a6paper]{geometry}
\usepackage{tikz}
\usepackage{lipsum}

\begin{document}

\foreach \x in {1,2,3,4}
{ \lipsum[\x]
    \includegraphics[scale=1]{pic\x.png}
    \clearpage
}

\end{document}

Alternatively, you can specify tuples of variable to iterate over. The following does the same:

\foreach \x/\picname in {4/pic1.png,8/pic2.png,15/pic3.png,16/pic4.png}
{ \lipsum[\x]
    \begin{figure}[htb]
        \includegraphics[scale=1]{\picname}
        \caption{The very nice picture \x}
    \end{figure}
    \clearpage
}

And the output being:
