It works fine here. The relevant function is org-link-expand-abbrev and
it depends on the variables org-link-abbrev-alist and
org-link-abbrev-alist-local.  The latter gets initialized from the
former and any #+LINK lines in the buffer are added on to it. In my
case, the first one is nil, so the second one is affected only by the
#+LINK lines in the org buffer. In the context of the org buffer
containing the link line, check that the variable is set:

        C-h v org-link-abbrev-alist-alist-local RET

should say that the variable has the value

  (("fig" . "file:/home/wilk/enseignement/doc_cours/optique/%s"))

If that is the case, then again in the context of the buffer,

    ESC ESC : (org-link-expand-abbrev "fig:test.jpg") RET

should return the expanded value


Hope this helps to track it down.

Closing and reopening the file should take care of the initialization
as well.
