I am working on a book which each chapter has an image .jpg or .png. The code that accomplishes this is:

newcommand{thechapterimage}{}

newcommand{chapterimage}[1]{renewcommand{thechapterimage}{#1}}

defthechapter{arabic{chapter}}

def@makechapterhead#1{

node[anchor=north west] at (1cm,.25cm) {parbox[t][8cm][t]{6.5cm}{hugebfseriesflushleft printcontents{l}{1}{setcounter{tocdepth}{2}}}};



draw[anchor=west] (5cm,-9cm) node [rounded corners=25pt,fill=white,fill opacity=.6,text opacity=1,draw=colordominante,draw opacity=1,line width=2pt,inner sep=15pt]{hugesffamilybfseriestextcolor{black}{thechapter --- #1vphantom{plPQq}makebox[22cm]{}}};

end{tikzpicture}};

end{tikzpicture}}parvspace*{230p@}

In the main document, you would call the name of a figure just before the chapter command:

chapterimage{imagen4.png} 

chapter{Estadística y probabilidad}

Whose generated image is

The question is whether it is possible to modify the previous code where a .tex file that directly draws the image is inserted, something like chapterimage{input{pascal.tex}} this because if only one image is included it loses quality.

I am not sure if this qualifies as an answer. However, if you do not convert your self-created image to png put just keep it in the pdf format, there won't be any quality loss.

The reason why I am posting an answer here is to tell you that you should really not nest tikzpictures. And there is no need for it either. You could just use this great answer to put whatever on top of your included graphics. Specifically, there is a local coordinate system coming with that answer which makes the placement a bit more intuitive. (Note that here because of the absolute positioning and the fact that the north west anchor is used, y becomes larger when moving down.) Your Preambulo.tex file then becomes
