How to organize the files in subfolders

I organize my presentacion in a folder with the name of the lecture and subfolders for papers and other for images. Hence, I will have /papers and /images folders. 

Then, 

• to insert a figure: \includegraphics{./images/file.png}
• to insert the references: \bibliography{./papers/references.bib}

Two figures with different captions in one slide

\begin{frame}{Ejemplos}

\begin{figure}[T]

\includegraphics<1>{image-1}
\includegraphics<2>{image-2}

\caption{\only<1>{caption of image-1}\only<2>{caption of image-2}}

\end{figure}
\end{frame}

Add watermark beamer

\usepackage{tikz}

\setbeamertemplate{background}{\tikz[overlay,remember picture]\node[opacity=.04]at (current page.center){\includegraphics[width=5cm]{watermark-image}};}

Fit table in beamer slide

\resizebox{\textwidth}{!}{%

\begin{tabular}

then add } after \end{tabular}

Hide navigation simbols

\setbeamertemplate{navigation symbols}{}

Use bibliography

\usepackage{hyperref}
\setbeamertemplate{bibliography entry title}{}

\begin{frame}[shrink=0]{Recommended reading} % adjust the shrink.
\bibliographystyle{amsplain} % use unsrt if no order is desired
\bibliography{./papers/references.bib}
\nocite{*}
\end{frame}

Hide some section in the index

\usepackage{appendixnumberbeamer}

\appendix %from here, nothing will appear in the outline

Change colors after appearing

\begin{itemize}

\item <1 -> {\only<2->{\color{gray}}First}

\item <2 -> {\only<3->{\color{gray}}Second}

\item <3 -> {Third}

\end{itemize}

Generate an outline

% Uncomment these lines for an automatically generated outline.
\begin{frame}[shrink=1]{\contentsname}
%\begin{multicols}{2} % for two columns
\tableofcontents
%\end{multicols}
\end{frame}

Cambiar cuadro por tabla
