Actually, your best bet here is to use vBulletin's "User Ranks" feature. With it, you can associate images or HTML with specific usergroups and it will be displayed in the location you specified.

However, if you would rather use a plugin, then you could use the code:

PHP Code:

$imagesrc = '';

if (is_member_of($post, array(14)))
{
    $imagesrc = '5dc09irbp/mh_MJw6_U.png';
}
elseif (is_member_of($post, array(32)))
{
    $imagesrc = 'h8jobvrud/gold.png';
}

if ($imagesrc)
{
    $image = '<img src="https://s32.postimg.org/' . $imagesrc . '" />';
    $template_hook['postbit_userinfo_left'] .= $image;
}
