Insert an image in a long text

Hi

CA51 can be used to print out a production routing, together with its header long text. I'm trying to put an image into the long text in transaction CA02
with the sentence below. BTW the image 'DRAWING 1' is already stored on server with SE78.

But then in the printout from CA51 I can only see this sentence output as a text rather than the image itself

Any idea please?
