Thanks for clarifying it, in the worg page:
--8<---------------cut here---------------start------------->8---
The standard :file header argument associated with a LaTeX source code
block by itself can take the name of either a Portable Network Graphics
(png) or a Portable Document Format (pdf) file. File names for other
bitmap file types can be supplied in conjunction with the :imagemagick
header argument, described below.
--8<---------------cut here---------------end--------------->8---
the "other bitmap file types" led me to believe that imagemagick was not
needed for png.

If it were to work, what would be the difference ? Would I need to add a 
command in the LaTeX code to print the name of the file I want to link
to ?

Thanks for your precious help. I'm always amazed at the responsiveness
and helpfulness of this list.
