Ok, I get it, and it works exactly like that with new version.

Just mumbling to myself that perhaps something like  python's
os.walk() might be faster than vim. So, forget it, as, at least
for me it's fast enough now.

Example:

I put my images (or links to them) in the directory

$HOME/texinputs

I have set the environment variable $TEXINPUTS to the above
directory. This means LaTeX will include the files in that
directory in its filename database.

Suppose I have a Document at

$HOME/Testdir/test.tex

Now, I write into test.tex:

\includegraphics{image}

[ just the basename ]

and if

$HOME/texinputs/image.jpg

exists, it is found and included in the (pdf)output.

Same thing happens if I have declared

\graphicspath{{/path/to/home/texinputs}}

[ See grfguide.ps ]

in my document (it only eats loads of LaTeX' resources when there
many files in that directory, or several directories).

This has the big advantage over declaring an absolute path that
in the case I move test.tex to eg.

$HOME/Anotherdirectory/test.tex

the document still compiles without changes.

Similarly when I decide to move the images to

$HOME/Images

I simply change $TEXINPUTS to $HOME/Images.

Whereas when I have absolute paths in my document I have to
change every path to every image.

Hope it has become clearer instead of more confusing.
