[wp-hackers] Images attached to posts/pages?

[Otto]

Attachments are essentially children of the post they're attached to.

They have the post_parent set to the id of the post, and they have a
post_type of "attachment".

To get attachments of a post:
$attachments = get_children( array('post_parent' => $post_id,
'post_type' => 'attachment') );

To only get image attachments:
$attachments = get_children( array('post_parent' => $id, 'post_type'
=> 'attachment', 'post_mime_type' => 'image') );


Once you have that, you can basically do this sort of thing:
foreach ( $attachments as $att_id => $attachment )
     echo wp_get_attachment_link($att_id, $size, true);

And so forth. There's several wp_get_attachment_* functions you can
use to get various bits from the attachment posts, once you have their
id's.
