I want babel can generate a figure image which path is relative to current
directory instead of full path.

Here is the org-mode buffer example which use `:dir "data/images"` as
default directory for executing code:


```
#+BEGIN_SRC gnuplot :session none :results graphics :dir "data/images"
:file "org-babel-plot-test.png"
set term png
set output 'org-babel-plot-test.png'

set grid

plot sin(x)
#+END_SRC

#+RESULTS:
[[file:/home/stardiviner/Org/Blog/org-publish/Blog/data/images/org-babel-plot-test.png]]
```

And here is another example which use current directory for save figure
image:

```
#+BEGIN_SRC gnuplot :session none :results graphics :file
"org-babel-plot-test.png"
set term png
set output 'org-babel-plot-test.png'

set grid

plot sin(x)
#+END_SRC

#+RESULTS:
[[file:org-babel-plot-test.png]]
```

What I want:
- result figure image can display as inline image.
- result figure image also can work in remote server. (like the first
example, `ox-publish` exported HTML link is local resource link like
`file:///home/USER/....png`)

Is there a way to change babel generate figure image result path to be like
option `org-link-file-path-type` can set to `adaptive`.

- I think org-mode should improve on this.
- If somebody can provide an adivce, that is good too for a solution to use
for now.
