Different background images per chapter page

Question

Each of my chapter titles are on a single page, with the content following on the following page. I have added a standard background image to each of those pages. What I'd like to do though, is to be able to add a different background image to each chapter. I was looking to do something like this:

\chapter{Another chapter}[background1.jpeg]
\chapter{Another chapter}[background2.jpeg]

And then be able to reference background1.jpeg and background2.jpeg in \titleformat as some sort of parameter. Is this possible?

Here's the full Latex:

\documentclass[11pt]{report}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{imakeidx}
\usepackage{lmodern}
\usepackage{titlesec}
\usepackage{eso-pic}
\usepackage{lipsum}

\titleformat{\chapter}[display]
{\vfill\filcenter}
{{%
    \filcenter\fontsize{24pt}{24pt}\usefont{T1}{phv}{m}{n}{\chaptername}
    \fontsize{24pt}{24pt}\selectfont\thechapter%
    \AddToShipoutPictureBG*{\includegraphics[width=\paperwidth,height=\paperheight]{"background.jpeg"}}
}%
}
{5pt}
{
\fontsize{48pt}{48pt}\selectfont%
}[\vfill\clearpage]
\titlespacing*{\chapter}{0pt}{0pt}{0pt}

\titleformat{name=\chapter,numberless}[display]
{\filcenter}
{{%
}%
}
{5pt}
{\Huge\usefont{T1}{phv}{b}{n}%
}

\begin{document}

\setcounter{chapter}{21}

\chapter{Chapter Title}
\section{Section one}
\lipsum[1]
\section{Section two}
\chapter{Another chapter}
\section{Section one}
\lipsum[2]
\end{document}

Try this code:

\documentclass[10pt,a4paper]{book}
\usepackage{graphicx,lipsum,emptypage}
\usepackage[placement=center]{background}
\begin{document}
    \chapter{One}
        \backgroundsetup{contents=To review,color=blue!30} %in place of 'To review' you put your image
        \newpage
        \backgroundsetup{contents=}
         % partial index of the chapter
    \chapter{Two}
        \backgroundsetup{contents=Confidential,color=blue!30} %in place of 'Confidential' you put your image
        \newpage
        \backgroundsetup{contents=}
        % partial index of the chapter
\end{document}
