How can i progmatically add image from custom list to word 2013 document??

I am trying to generate formatted doc files for my each list items using SharePoint 2013.

Till now i am following this page and partially succeeded

but the problem that i am facing right now is that i am unable to add list picture in formatted doc files.  

i tried a work around by using 'List Item Image URL' as document property and used it as a field in quick field "INCLUDEPICTURE". but this solution requires field update every time after opening it in word 2013 (i.e hotkey F9)..........[and F9 does not work if i protect my Doc library with AD RMS and IRM]

Any solutions/recommendations???
