By default this option isn't available. But you can add it by simple
1. Download, install and publish JComments Avatar plugin
2. Enable JComments mambots (plugins) in module params
3. Change mod_jcomments by replacing:
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . $row->name;
with:
if ($row->profileLink != '') {
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . '<a href="'.$row->profileLink.'">' . $row->name . '</a>';
} else {
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . $row->name;
}
and
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . $row->name;
with:
if ($row->profileLink != '') {
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . '<a href="'.$row->profileLink.'">' . ($row->username ? $row->username : $row->name) . '</a>';
} else {
echo '<br />' . ($label4author != '' ? $label4author . ' ' : '') . ($row->username ? $row->username : $row->name);
}
