Description

I want to integrate graphics from a folder into the titlepage. But there always is an issue.

My folder-structure is this:

My Quarto YAML:

---
title: "Titel"
subtitle: "Untertitel"
author:
  - "Max Mustermann"
  - "Maria Musterfrau"
date: today
lang: de
format:
  pdf:
    documentclass: scrbook
    keep-tex: true
    toc: true
    toc-depth: 3
    lof: true
    lot: true
    number-sections: true
    include-in-header:
      - "templates/header_footer.tex"
    template-partials:
      - "templates/before-body.tex"
      - "templates/_titlepage.tex"
      - "templates/doc-class.tex"
fontsize: 11pt
linestretch: 1.5
geometry: left = 25mm, right = 25mm, top = 30mm, bottom = 30mm
bibliography: bosch.bib
execute: 
  echo: false
  warning: false
  message: false
editor: visual

The latex-code in _titlepage.tex to include the graphic:

\includegraphics[width=1.8in]{Bilder_Titelseite/HBC_Logo.png}

i also tried:

\includegraphics[width=1.8in]{./Bilder_Titelseite/HBC_Logo.png}

the issue by rendering:

I'm sorry.
It was my fault.
I included the same graphic a second time in the document. So i had to put it in the main folder...
