Going by this http://codex.wordpress.org/Function_Reference/wp_get_attachment_metadata, this should help, but doesn’t:
<?php wp_get_attachment_metadata( $attachment_id, $unfiltered ); ?>

Can someone please assist?

Thank you

  1. wp_get_attachment_metadata result is:

    Array
(
    [width] =>
    [height] =>
    [file] =>
    [sizes] => Array
        (
            [thumbnail] => Array
                (
                    [file] =>
                    [width] =>
                    [height] =>
                    [mime-type] =>
                )

            [medium] => Array
                (
                    [file] =>
                    [width] =>
                    [height] => 
                    [mime-type] => 
                )

        )

    [image_meta] => Array
        (
            [aperture] => 
            [credit] => 
            [camera] => 
            [caption] => 
            [created_timestamp] => 
            [copyright] => 
            [focal_length] => 
            [iso] => 
            [shutter_speed] => 
            [title] => 
        )

)

    So, this is attachment datails. But you want get custom fields. You can use same as post:

    get_post_meta($post->ID, 'your_field_name', true);

    all of which avaible in attachment.php. In attachment page, $post is attachment post, so not parent post.
