I am trying to set different backgrounds in each page of my LaTeX document. I have tried with tikz, background and many other packages I found, but I couldn't.
I.E.
First page: \maketitle
with one background
Second page: \tableofcontents
with a different background
Third pages and following: Content with another background
[Edit 1]
There is something I didn't explain well. Your code helped me a lot, but I tried to modify it and had some problems.
\documentclass[a4paper, 12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{eso-pic}
\usepackage[spanish]{babel}
\usepackage[absolute,overlay]{textpos}
\usepackage{xcolor} \definecolor{letras_portada}{RGB}{229,238,245}
\begin{document}
\AddToShipoutPictureBG*{\includegraphics[width=\paperwidth,height=\paperheight]{First_page.png}}
\begin{textblock*}{15cm}(6.35cm,23cm)
\huge{\textcolor{letras_portada}{\textbf{Report}}}
\end{textblock*}
\cleardoublepage
\AddToShipoutPictureBG*{\includegraphics[width=\paperwidth,height=\paperheight]{Index.png}}
\paragraph{}
\clearpage
\AddToShipoutPictureBG{\includegraphics[width=\paperwidth,height=\paperheight]{Content.png}}
\tableofcontents
\clearpage
\section{section 1}
text example 1text example 1text example 1text example 1text example 1text example 1text example 1text example 1text example 1text example
\subsection{2}
text example 1text example 1text example 1text example 1text example 1text example 1
\subsubsection{3}

\end{document}
What I pretend as is to have a first page with my title (instead of maketitle I a text), a second page with an specific background but without text and in the third page I'd like to have the table of contents. But second page disappear.
One possibility is the eso-pic
package. With \AddToShipoutPictureBG*{}
you can change the background of the current page, with \AddToShipoutPictureBG{}
of the current and all following pages.
\documentclass{book}
\usepackage{graphicx}
\usepackage{eso-pic}
\author{names}
\title{title}
\begin{document}
\AddToShipoutPictureBG*{\includegraphics[width=\paperwidth,height=\paperheight]{example-image-duck}}
\maketitle
\cleardoublepage
\AddToShipoutPictureBG*{\includegraphics[width=\paperwidth,height=\paperheight]{example-image-a}}
\tableofcontents
\clearpage
\AddToShipoutPictureBG{\includegraphics[width=\paperwidth,height=\paperheight]{example-grid-100x100bp}}
\chapter{title}
text
\end{document}
To add background only pages in a one sides documentclass, you could use this quick hack:
\documentclass[a4paper, 12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{eso-pic}
\usepackage[spanish]{babel}
\usepackage[absolute,overlay]{textpos}
\usepackage{xcolor} \definecolor{letras_portada}{RGB}{229,238,245}
\begin{document}
\AddToShipoutPictureBG*{\includegraphics[width=\paperwidth,height=\paperheight]{example-image-a}}
\begin{textblock*}{15cm}(6.35cm,23cm)
\huge{\textcolor{letras_portada}{\textbf{Report}}}
\end{textblock*}
\mbox{}
\newpage
\mbox{}
\AddToShipoutPictureBG*{\includegraphics[width=\paperwidth,height=\paperheight]{example-image-b}}
\newpage
\AddToShipoutPictureBG{\includegraphics[width=\paperwidth,height=\paperheight]{example-image-c}}
\tableofcontents
\clearpage
\section{section 1}

\subsubsection{3}

\AddToShipoutPictureBG{\includegraphics[width=\paperwidth,height=\paperheight]{example-image-b}}
