Correct way of using wp_get_attachment_image() in wordpress

I'm looking for the correct way of using wp_get_attachment_image().

The following code:

<?php
$args = array(
'type' => 'attachment',
'category_name' => 'portfolio'
);
$attachments = get_posts($args);
print_r($attachments);
?>


Generates the following result:

Array
(
[0] => stdClass Object
(
[ID] => 54
[post_author] => 1
[post_date] => 2010-06-22 00:32:46
[post_date_gmt] => 2010-06-22 00:32:46
[post_content] => <a href="http://localhost/wordpress/wp-content/uploads/2010/06/Capture.jpg"><img class="alignnone size-medium wp-image-55" title="Capture" src="http://localhost/wordpress/wp-content/uploads/2010/06/Capture-300x114.jpg" alt="" width="300" height="114" /></a>
[post_title] => Our Own Site
[post_excerpt] =>
[post_status] => publish
[comment_status] => open
[ping_status] => open
[post_password] =>
[post_name] => our-own-site
[to_ping] =>
[pinged] =>
[post_modified] => 2010-06-22 00:40:22
[post_modified_gmt] => 2010-06-22 00:40:22
[post_content_filtered] =>
[post_parent] => 0
[guid] => http://localhost/wordpress/?p=54
[menu_order] => 0
[post_type] => post
[post_mime_type] =>
[comment_count] => 0
[filter] => raw
)
)


The following, however, doesn't return anything.

<?php
echo wp_get_attachment_image(54, array('300', '300'));
?>


What am I doing wrong here?

Answer

The function wp_get_attachment_image only gets an image that was uploaded to wordpress, it doesn't output an image in the content of the post.

You have to output the content of the post for your example image.

Like: echo $attachments['post_content'];
