thanks for your help.
No i'did not want upload the images by Komento.
I can upload by other extension.
For example i can upload the avatar image by http://extensions.joomla.org/extensions/extension/clients-a-communities/user-management/cmavatar
But then i need to display the cmavatr on the Komento comment.
Cmacatar said that to display its avatar in other extensio you need to create the url by this small helper:
require_once JPATH_PLUGINS . '/user/cmavatar/helper.php';
$avatar = PlgUserCMAvatarHelper::getAvatar($userId);
$userId is the variable which holds the ID of the user of you want to get his/her avatar.
The result in $avatar is the path to the avatar of the user, for example “images/avatars/4d99b38d96ed65caf39fde008528f185.jpg”, you can do whatever you want with it like put it into <img> HTML element. If user doesn’t have avatar, the result is empty.
Then, where i can implement this on Komento.
I mean where is the file.php where Komento display the avatar?
