There is also gravatar which is likely trying to be reached in Manager requests as well. We're looking at ways to get MODX to know whether it can connect to the internet and to disable these, however this may be a problem until at least 2.3.1 for the gravatar call.
public function getUserImage() { /** @var modUserProfile $userProfile */ $userProfile = $this->modx->user->getOne('Profile'); if ($userProfile->photo) { // First, handle user defined image $src = $this->modx->getOption('connectors_url', MODX_CONNECTORS_URL) .'system/phpthumb.php?zc=1&h=128&w=128&src=' .$userProfile->photo; $userImage = '<img src="' . $src . '" />'; } else { /* // Fallback to Gravatar $gravemail = md5( strtolower( trim($userProfile->email) ) ); $gravsrc = $this->modx->getOption('url_scheme', null, 'http://') . 'www.gravatar.com/avatar/' .$gravemail . '?s=128'; $gravcheck = $this->modx->getOption('url_scheme', null, 'http://') . 'www.gravatar.com/avatar/' .$gravemail . '?d=404'; $response = get_headers($gravcheck); if ($response != false) { $userImage = '<img src="' . $gravsrc . '" />'; } else { $userImage = '<i class="icon-user icon-large"></i>'; } */ $userImage = '' ; } return $userImage; }
