Includegraphics problems with a PNG

Question

I have problems to insert an image into my .tex file. This is the code:

\begin{figure}
 \includegraphics[width=1\textwidth]{Blockdiagram}
  \caption{Diagram}
  \label{figure:BlockDiagram}
\end{figure}

It says that it cannot find the file! The same with Blockdiagram.png.

The figure is in the same folder. The main .tex is outside this folder, and I tried copying the image there, but the problem persists.

If I type H for help I have:

I could not locate the file with any of these extensions: .eps, .ps....

It's a png! In the file I have both:

\usepackage{graphicx}
\usepackage{epsfig}

And I tried commenting epsfig.... but nothing happens. Same error.

Any ideas?

EDIT: I have several PNG files, is it possible to use PNG files? I am using LEd under WinXP.

Answer 1

You could use PDFLaTeX instead of LaTeX. PDFLaTeX can import PNG images. You cannot use EPS images in PDFLaTeX, though; you would have to use PDF as a vector image format. I would recommend to use ImageMagick to convert images.
