   ==Question== hi when I look at http://en.wikipedia.org/wiki/Arunachal_Pradesh , put it into edit mode to see there is reference to http://upload.wikimedia.org/wikipedia/commons/thumb/6/63/Arunachal_Pradesh_locator_map.svg/235px-Arunachal_Pradesh_locator_map.svg.png the only reference I have found out is in the infobox saying something like |inset_map_marker     = yes but nothing more, can somebody tell how it works? ]]
