* Does Org-mode `:output-dir` header-argument? Or is `:dir`?

* An example

I can make it (`:results file :file "FILENAME"`) work in `ob-python` like
this:

```org
#+BEGIN_SRC python :var fname="QR_I_Love_YOU.png" :dir "data/images"
:results file
import qrcode

img = qrcode.make("I Love YOU")
img.save(fname)
return fname
#+END_SRC

#+RESULTS:
[[file:/home/stardiviner/Org/Wiki/Computer
Technology/Programming/Programming
Languages/Python/Data/Packages/data/images/QR_I_Love_YOU.png]]
```

* More specific suggestion:

Make use of org-mode variable `org-link-file-path-type`.
When user generate a result with link (like:

```org
#+RESULTS:
[[file:/home/stardiviner/Org/Wiki/Computer
Technology/Programming/Programming
Languages/Python/Data/Packages/data/images/QR_I_Love_YOU.png]]
```

Org-mode babel always use relative file path for link, instead of absolute
file path like upper example.
For example, if current path is `/home/stardiviner/Org/Wiki/Computer
Technology/Programming/Programming Languages/Python/Data/Packages/`, then
the relative file path link should be:

```org
#+RESULTS:
[[file:data/images/QR_I_Love_YOU.png]]
```

* About what one preceduce over the other problem

The header argument `:dir "data/images"` is used to specify my generated
image's destination directory.
My suggestion is want a the result link use `org-link-file-path-type`. So
the header argument `:dir` is not about the result link. Just it will be
used. Like upper example.
