Thanks Nick, a typo :)

I changed that and added ``:file "fig1.png"'' in header so now HTML has both: code
and image.

>> size(100);

So I don't get the idea of ``#+CALL''. It doesn't work in this case. I
thought I can show code and after small explanation the resulted
image. But seems I'm allowed to get PNG file only with BEGIN|END_SRC
block while image be placed right after the block.

I came to this:

#+NAME: fig1
#+BEGIN_SRC asymptote :exports both :results silent :file "fig1.png"
<<CODE>>
#+END_SRC

Result:\\
[[./fig1.png]]

This is essential that I want.

Thanks again.
