Edwards, all I can tell is that currently username displayed within the console comes from /ow_system_plugins/base/classes/console_event_handler.php :

if ( OW::getUser()->isAuthenticated() )
        {
           $item = new BASE_CMP_ConsoleDropdownMenu(BOL_UserService::getInstance()->getDisplayName(OW::getUser()->getId()));
            $item->setUrl($router->urlForRoute('base_user_profile', array('username' => OW::getUser()->getUserObject()->getUsername())));
            $item->addItem('main', array('label' => $language->text('base', 'console_item_label_profile'), 'url' => $router->urlForRoute('base_user_profile', array('username' => OW::getUser()->getUserObject()->getUsername()))));
            $item->addItem('main', array('label' => $language->text('base', 'edit_index'), 'url' => $router->urlForRoute('base_edit')));
            $item->addItem('main', array('label' => $language->text('base', 'preference_index'), 'url' => $router->urlForRoute('base_preference_index')));
            $item->addItem('foot', array('label' => $language->text('base', 'console_item_label_sign_out'), 'url' => $router->urlForRoute('base_sign_out')));

You will need to edit this code ( using BOL_AvatarService ) and most likely console's .html files to be able to display avatars there.

This is not a complex change, but requires very good knowledge of .php. Unfortunately I can not provide you with detailed instructions. You will need to investigate this further and try on your own. May be other community members will be able to help you.

hay can you please inbox me ..  i just want to replace console user name with user avatar .

Unfortunately I can not provide more detailed information on this, since this will require creating additional code and quite a lot of experimenting with the console.

thanks

This might be a nice optional setting for a future build?

Display username, Display Avatar, Display username and Avatar?
