I'm using Wordpress Custom Area Template Wordpress plugin - http://wordpress.org/extend/plugins/custom-field-template/

I create some File filed such as this

[slideshow]
type = file
relation = true
label = Images For the Slide show?

[slideshow]
type = file
relation = true
hideKey = true

[slideshow]
type = file
relation = true
hideKey = true

[slideshow]
type = file
relation = true
hideKey = true

And I wish to show list the pictures in the file fields something similar to

<?php $slide_images = get_post_meta($post->ID, 'slideshow', false); ?>
   <ul id="slideshow">
                <?php foreach($slide_images as $slide_image) {
                    echo '<li>'.$slide_image.'</li>';
       } ?>
  <ul>

Got the answer

<?php $slide_images = get_post_meta($post->ID, 'slideshow', false); ?>
            <ul id="slideshow">
                <?php  foreach($slide_images as $key=>$slide_image) {
                    $slide_url = wp_get_attachment_image($slide_image, 'full');
                    echo '<li>'.$slide_url.'</li>';
} ?>
