[O] How to auto insert inline image link for org-plot/gnuplot result plot?

[address@hidden]

I want to auto insert inline image for `org-plot/gnuplot` result plot below the table. Like this:

```org

#+PLOT: title:"Citas" ind:1 deps:(3) type:2d with:histograms set:"yrange [0:]"

| Sede      | Max cites | H-index |

|-----------+-----------+---------|

| Chile     |    257.72 |   21.39 |

| Leeds     |    165.77 |   19.68 |

| Sao Paolo |     71.00 |   11.50 |

| Stockholm |    134.19 |   14.33 |

| Morelia   |    257.56 |   17.67 |

Press =[C-c " g]= on upper table to generate gnuplot plot image (*NOTE*: the

generated plot image is in currently working directory).

#+ATTR_ORG: :width 250

#+ATTR_LATEX: :width 2.5in

#+ATTR_HTML: :width 250px

[[file:org-plot.png]]

```

I have an idea, add an advice on `org-plot/gnuplot` with a user helper function to inser the inline image link.

This advice need to:

- locate point below the table.

- get the `org-plot/gnuplot` result plot image link.

- insert inline image link.
