Like example, here is a code from commercial script arrowchat, to return url of the avatar in ELGG 1.8.5:
/**
* This function returns the URL of the avatar of the specified user ID.
*
* @param userid the user ID of the user
* @param image if the image includes more than just a user ID, this param is passed
* in from the avatar row in the buddylist and get user details functions.
* @return the link of the user ID's profile
*/
function get_avatar($image, $user_id)
{
global $base_url;
return $base_url . "../mod/profile/icondirect.php?joindate=" . $image . "&guid=" . $user_id . "&size=medium";
}
