Picture/Logo in Header Quarto qmd to pdf

Question

I want to place a logo in the header of the first page of an article(documentclass: scrartcl), but I want the header to change from the second page onward. I have tried the following solution:

---
title: "Logo in Header"
format: 
   pdf: 
      include-in-header: 
         text: |
            \usepackage{scrlayer-scrpage}
            \clearpairofpagestyles
            \cohead[\includegraphics[width=5cm]{my_logo.png}]{Header from page 2 onward}
            
---

Page 1

\newpage

Page 2

Unfortunately, I am receiving the following error message:

compilation failed- error
LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.80 ...cludegraphics[width=5cm]{visana_logo.png}]
                                                  {Header from page 2 onward}

When I replace the image with text, it works:

---
title: "Logo in Header"
format: 
   pdf: 
      include-in-header: 
         text: |
            \usepackage{scrlayer-scrpage}
            \clearpairofpagestyles
            \cohead[Header page 1]{Header from page 2 onward}
            
---

Page 1

\newpage

Page 2

It also works when I remove the width argument for the image:

---
title: "Logo in Header"
format: 
   pdf: 
      include-in-header: 
         text: |
            \usepackage{scrlayer-scrpage}
            \clearpairofpagestyles
            \cohead[\includegraphics{my_logo.png}]{Header from page 2 onward}

Answer 1

You are getting errors because the closing square bracket ] from width[..] is being parsed as optional argument terminator for \cohead.

So, \includegraphics[width=5cm is being passed as the optional argument to \cohead. So to avoid this, enclose the whole optional argument content within a curly braces. See this excellent Q/A thread from TexStackExchange for details.

Therefore, just put the includegraphics[width=5cm]{test.png} within a extra pair of curly braces {} and it will work!
