If your doing a presentation in LaTeX using the beamer class, a nice feature of it is that you may add a background picture to your PDF file in both, a global or individual way.
Global Setting of Background:
In the preamble of your TEX file write the command
\usebackgroundtemplate{\includegraphics[width=\paperwidth,height=\paperheight]{<file_name>}
Remember that: if your image file is not in the same folder than your TEX file, but in a sub folder you must give the sub-folder address as well.
Individual Setting of Background:
For a individual setting, write the same line as above just before the \begin{frame} command of the frame you want to edit, and then wrap it all with braces.
{
\usebackgroundtemplate{\includegraphics[width=\paperwidth,height=\paperheight]{<file_name>
\begin{frame}
\titlepage
\end{frame}
}
Enjoy!
