How to create a command for the sections with an svg next to it on the top of the page?

Question

This is an addendum of a previous question: How to place a \draw near the page number using tikzpicture environment.

---

What I want

I would like to have the section text moved to the top of every page, and place an image next to it. Look at this:

Why I mention sections? Because when the document is finished I want to make a ToC at the beginning.

• The image (svg file) is always the same.

For example:

• The full document has 8 pages in total.
• In page 1 there should be nothing.
• In pages 2-4, the green rectangle should have: Section One: Text with the image next to it.
• In pages 5-7, the green rectangle should have: Section Two: More text with the image next to it.
• In page 8, the green rectangle should have: Bibliography with the image next to it.

and we should be able to produce a ToC with those 3 sections (two sections and the bibliography).

What I have done

Consider this MWE (taken from the accepted answer of the addendum):

Problems:

• I don't know how to use \newcommand[1]{\sec}{...} to have different sections on pages, where the argument is the name of the section.
• The cropped image does not show on the 2.5cm circle (inside \begin{document}). (I have loaded graphicx and put \graphicspath. I tried with \includegraphics{Example.png} outside tikzpicture and it worked.)

Answer 1

One way is to use titlesec. That way you can use ordinary \section commands for that purpose. This has various advantages (table of contents, hyperlinks, ...). You then only need to type

\section{I am a cat}
Example
\newpage 
\section{You are a duck}
Another example

in the body of your document.
