Easy Profile - Joomla Extension

Hi,
to make this you need some integration plugin (like kunena), unfortunately we not have experience with corejoomla components so we can't help you. Anyway you can request this feature directly to CoreJoomla developers, it should be simple for they because with our APIs you can retrieve avatar and profile link with 3 lines of PHP code:

require_once( JPATH_SITE . '/components/com_jsn/helpers/helper.php' ) ;

echo JsnHelper::getUser( $user_id )->getField( 'avatar' ); // Avatar

echo JsnHelper::getUser( $user_id )->getLink(); // Profile Link

About Jomsocial Bridge:
this plugin simulate an installation of Jomsocial, so all component that have some integration with Jomsocial should retrieve Avatar and Profile link from Easy Profile, here an example with Community Answer:
- from https://www.corejoomla.com/products/community-answers.html I see that Community Answer have integration with Jomsocial avatars (but not with Easy Profile avatars)
- Install Easy Profile, Community Answer and Jomsocial Bridge
- Set Community Answer to use Jomsocial avatar
- You should see Easy Profile avatar in your frontend, of course as you can see from doc page at http://docs.easy-profile.com/index.php/article/jomsocial-bridge it is not tested with "Community Answer" so you need to try it before.

Due to nature of Jomsocial Bridge you can't install it with Jomsocial component. otherwise it will break your Jomsocial installation.

Possible Alternative
Probably there are many other ways to make this, for example it's possible that you does not need of Jomsocial bridge, here another example:
- Install Easy Profile, Community Answer and Kunena
- Kunena have a natively integration with Easy Profile, so you can enable and configure dedicated plugin
- Set Community Answer to use Kunena avatar
- Community Answer should retrieve avatar from Kunena and Kunena retrieve avatar from Easy Profile, you probably you have the result as example above with Jomsocial Bridge.

NOTE: Keep in mind that we not have any experience with CoreJoomla components, so I'm not sure it works.

About Jomsocial
Sorry but I don't know if Jomsocial allow you to use avatar from others components.
