Sounds like a cool feature. The good news: we do use a single Freemarker macro for every place that we display a username. The bad news is that the macro is in a file that we don''t currently support overriding so if you want to do this, you''ll have to look for the instances of
<@jive.userDisplayNameLink user=user />
in the content lists you want to change and then either replace it inline or write your own macro that looks at the group the user is in and displays either the corporate employee logo or the field employee logo.
+1 for us -- we wanted to stick company icons where appropriate on author names but could not easily.
