I am not familiar with that variable.
This variable has some influence on the appearance of images: org-image-actual-width. Note it needs imagemagick support which is tricky on windows sometimes.
org-image-actual-width is a variable defined in `org.el'.
Its value is nil
Original value was t
Documentation:
Should we use the actual width of images when inlining them?
When set to t, always use the image width.
When set to a number, use imagemagick (when available) to set
the image's width to this value.
When set to a number in a list, try to get the width from any
#+ATTR.* keyword if it matches a width specification like
#+ATTR_HTML: :width 300px
and fall back on that number if none is found.
When set to nil, try to get the width from an #+ATTR.* keyword
and fall back on the original width if none is found.
This requires Emacs >= 24.1, build with imagemagick support.
