I can't insert an image placeholder on header

I need to insert an image logo at every page on a document. I’ve tried using placeholder <$img:…> referring to an image imported to Resources folder, then I’ve edited page settings in section compile, I write the image placeholder at header, but when the compiling is made, no image appears.
What am I doing wrong?

The old post linked below, authored by the developer of Scrivener, explains that images can’t be added to headers. I think this limitation is still true today. The advice is to add the image after compiling.
