images overrides

I'd like to use the joomla image override for EasySocial for the default avatars and covers that are located in the joomla/media/com_easysocial folder. What would the proper path be for the template? For example for the existing file:
media/com_easysocial/defaults/covers/user/default.png

I've tried unsuccessfully:
templates/elegant/images/com_easysocial/defaults/covers/user/default.png
