Q:

Uploading avatar from the frontend

in the codepad link you can find what I am using to edit profile from the front-end.  http://codepad.org/QJjDEA7p
The code is working (which I got from How to edit a user profile on the front end?  and change some things for me to work correctly). 
I have installed Simple Local Avatar plugin to allow avatar uploading, but how can I modify the code to have it also from the front-end ?  I found these below, which I tested, showed the upload button, did not showed the current avatar and didn't let me to change it. 
Thank you for your help on this. 
do_action('show_user_profile');
do_action('edit_user_profile');

do_action('personal_options_update');
do_action('edit_user_profile_update');

UPDATE
There goes a 50 bounty for a working example.  Unfortunately I can not get Bainternet's example to work that I tested with User Avatar plugin also, and I am really stuck with this issue can't finding the solution. 

A:

You only need to of these hooks show_user_profile to show the extra fields and  personal_options_update to update, try:
<? php
ob_start();
include_once("../../../wp-load.php");
get_header(); 

/* Get user info. */ 

global $current_user, $wp_roles;
get_currentuserinfo();

/* Load the registration file. */ 
require_once( ABSPATH .  WPINC . ' /registration.php' );

/* If profile was saved, update profile. */ 
if ( 'POST' == $_SERVER['REQUEST_METHOD'] && ! empty( $_POST['action'] ) && $_POST['action'] == 'update-user' ) {

    /* Update user password. */ 
    if ( ! empty($_POST['pass1'] ) && ! empty( $_POST['pass2'] ) ) {
        if ( $_POST['pass1'] == $_POST['pass2'] )
            wp_update_user( array( 'ID' => $current_user->id, 'user_pass' => esc_attr( $_POST['pass1'] ) ) );
        else
            $error = __('The passwords you entered do not match.   Your password was not updated.', ' profile');
    }

    /* Update user information. */ 
    if ( ! empty( $_POST['url'] ) )
        update_usermeta( $current_user->id, 'user_url', esc_url( $_POST['url'] ) );
    if ( ! empty( $_POST['email'] ) )
        update_usermeta( $current_user->id, 'user_email', esc_attr( $_POST['email'] ) );
    if ( ! empty( $_POST['first-name'] ) )
        update_usermeta( $current_user->id, 'first_name', esc_attr( $_POST['first-name'] ) );
    if ( ! empty( $_POST['last-name'] ) )
        update_usermeta($current_user->id, 'last_name', esc_attr( $_POST['last-name'] ) );
    if ( ! empty( $_POST['yim'] ) )
        update_usermeta($current_user->id, 'yim', esc_attr( $_POST['yim'] ) );
    if ( ! empty( $_POST['description'] ) )
        update_usermeta( $current_user->id, 'description', esc_attr( $_POST['description'] ) );

    //extra fields (simple local avatars ....)
        do_action('personal_options_update', $current_user->id);

    /* Redirect so the page will show updated info. */ 
    if ( ! $error ) {

header("Location: ".$_SERVER['PHP_SELF']);

        exit;
ob_flush();
    }
}
