What's the best way to write over an image?

I’m trying to write text over an image like this exemple:

I’ve read a lot about this topic but as I’m quite a beginner with Latex I’m lost (I’m using Overleaf with pdflatex btw).

I did the exemple with this code:

preambule.tex
usepackage{pst-all}
usepackage[miktex]{pdftricks} 
usepackage{auto-pst-pdf}

main.tex
input{preambule}
begin{document}
begin{pspicture}(2.6,0)(21,3)
  uput[ur](0,0){includegraphics[width=20.6cm,height=3cm]{images/Bandeau.jpg}}
  uput[u](10,2){textbf{LARGE{Rapport 1 mois de stage}}}
  uput[u](10,1){textbf{large{JLR}}}
  uput[u](10,0.5){textbf{4A GBM}}
  uput[u](10,0){textbf{Octobre 2020}}
end{pspicture}

section{Environnement}

But I still have some warnings that I don’t really understand:

Package pdftricks Warning: **************************************** No write 18 capability. You’ll have to run a script by yourself! ****************************************.

Package pdftricks Warning: **************************************** Package pdftricks v,1.16 loaded [psTricks support in PDF (CVR, ACL)] ****************************************.

So, I would like to know if it is a good solution and how I can remove those warnings. Or do I have to use tikz (such as this answer) even if I find it more difficult than pstricks ? What’s the real difference(s) between this two solutions?

I’ve also read about
pdftex--shell-escape or write18 but I don’t know where to introduce it in my document because I do not use commands.

Well, if someone can clarify those points…
Thanks!
