it seems that for every easysocial profil, Avatar and poster photoalbum are automatically created. Is there a way to prevent that from happening and/or erase those album for other profil to see with keeping the avatar picture on the profile picture

Avatar and poster photo album are automatically created if you upload picture for your avatar and cover photos. It is because the photos album is use to stored all uploaded photos for later use like Facebook and etc.

But, you can do some modification/replace uploaded attachment at this file ...\media\com_easysocial\apps\event\photos\widgets\events\view.html.php.

//add and replace this code at this line 94

 $options = array(

            'core' => false

        );



        $albums = $model->getAlbums($event->id, SOCIAL_TYPE_EVENT, $options);

Note: For further use, you need to backup this file for update/upgrade purpose as this will set to default settings and any modification done will be lost.
