Justin Tadlock’s Get-the-Image-plugin. Works like a charm.
First, get the image attachments of the post:
global $post;
$attachments = get_children( array(
'post_parent' => $post->ID,
'post_type' => 'attachment',
'post_mime_type' => 'image',
'orderby' => 'menu_order ASC, ID',
'order' => 'DESC') );
Next, go through them:
foreach ( $attachments as $id => $attachment ) {
// do whatever you want here with the $id being the $attachment_id
}
Like that.
Hello, I’m trying to do exactly that but, which could be an example of the use of the $attachment_id ? Just for print the thumbnail i.e. ?
I enjoy this plugin. It also has some great options in the settings.

Upload/activate the plugin, then use <?php the_thumb(); ?> inside the loop to display the first image added to your posts/pages.
If you are using the_content in this loop, and inserted your first uploaded image within the post. You can use preg_replace as shown below to strip the img tags from the_content. This way to can display your thumbnails as above however you want and have text only in the_content. Replace your the_content line with below to do so.
<?php
ob_start();
the_content(‘Read the full post’,true);
$postOutput = preg_replace(‘/<img[^>]+./’,”, ob_get_contents());
ob_end_clean();
echo $postOutput;
?>
Using both examples, you can do some nifty stuff for example float left on the thumbnail, to text wrap the post title, etc as well as the content.
