Not true.  The following seems to create the LaTeX code you wanted:

--8<---------------cut here---------------start------------->8---
#+attr_latex: :options {0.7\textwidth}
#+begin_minipage

#+CAPTION: looooooong caption.
[[file_path]]

#+end_minipage
--8<---------------cut here---------------end--------------->8---
