i’m trying to learn the way for uploading image file through custom field but cant get the easiest code to do it. i just done a bit here: 

add_action('admin_init', 'create_image_box');
function create_image_box() {
add_meta_box( 'meta-box-id', 'Image Field', 'display_image_box', 'post', 'normal', 'high' );
}

//Display the image_box
function display_image_box() {
 global $post;
  $image_id = get_post_meta($post->ID,'xxxx_image', true);
 echo 'Upload an image: <input type="file" name="xxxx_image" id="xxxx_image" />';

// Upload done: show it now...(as thmbnail or 60 x 50)

  1. Lets go Stepwise here:

    1. Create custom field Meta Box for inserting Image Url in post type => post.
    2. Update/Save the custom field value in back end.
    3. Display the custom field value in front end.

    Seeing your code it seems that you are missing #2. Try the code below to save custom field:

    function save_joe_details($post_id){
  global $post;
  if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE )
  return $post_id;
  update_post_meta($post->ID, "custom_field_image", $_POST["custom_field_image"] );
}
add_action('save_post', 'save_joe_details');

    Code for #3 that displaying the custom field will be:

    <?php global $post;
$custom_image = get_post_custom($post->ID); ?>
<img src="<?php echo $custom_image["custom_field_image"][0] ?>" />
