Hi All,
This patch improves the result of running org-plot in the following
situation
#+plot: ... file:"somefile.png"
[[file:somefile.png]]
Previously, when somefile.png is re-plotted the [[file:]] inline image
did not refresh. With this patch, after plotting, overlays of the
replotted image are refreshed.

Subject: [PATCH] org-plot: Refresh inline images after plotting
* lisp/org-plot.el (org-plot/redisplay-img-in-buffer): New function
which searches the current Org buffer for overlays of a certain image,
and refreshes those overlays.
(org-plot/gnuplot): Use `org-plot/redisplay-img-in-buffer' after
plotting to redisplay any associated inline images.
