Header content doesn't display media

Hi there,

my final goal is to display some content in 2 columns of a modular. Both can be text, images, pdf, etc.

The idea I started with was to create a blueprint extending default.
I added another editor. It works perfectly until I try to display images (local or on Internet).
In my theme template I call the editor content {{ header.colonne2|markdown }}. The markdown works for text styles but my images are still not displayed.

Any idea how I could manage that?

Thanks in advance
