Profile Pic Installed on a subdirectory

There appears to be path issues when WP is installed on a sub-directory.

Why do you use ABSPATH rather then $_SERVER[‘DOCUMENT_ROOT’]?

My edit

function profilepic_internal_picpath($authorID, $display = true, $type = ‘url’) {
switch($type) {
case ‘url’ :
$ref = profilepic_internal_cleanpath(profilepic_internal_pickimage($authorID));
if ($display) { echo $ref; } else { return $ref; }
break;
case ‘absolute’:
$ref = profilepic_internal_cleanpath($_SERVER[‘DOCUMENT_ROOT’] . profilepic_internal_pickimage($authorID));
if ($display) { echo $ref; } else { return $ref; }
break;
}
}
