Overrides for Registration

Hi,

I just changed the following file to re-order the fields for registration (the user flow was strange - the description, ie. upload a square image, was immediately below the image selection gallery):
media/com_easysocial/apps/fields/user/avatar/themes/default/content.php

Just wondering - I tried to create an override for this file in the following directory but it doesn't seem to work..
/public_html/templates/ja_obelisk/html/media/com_easysocial/apps/fields/user/avatar/themes/default/

Is this because the original file is in /media ? If so, is there a way to create an override for this?

Cheers, David
