[wp-hackers] get attachment ID when hijacking Media Library send_to_editor

[Rafael Ehlers]

You are saying something like this:

$thumbnail_id = get_post_meta( $post->ID, '_thumbnail_id', true );
$img = wp_get_attachment_thumb_url( $thumbnail_id );
echo "<img src=\"$img\">";

or

$thumb = wp_get_attachment_image( $thumbnail_id, 'thumbnail', true );

or

$attachments = get_children( array('post_parent' => $post->ID, 'post_type'
=> 'attachment', 'post_mime_type' => 'image') );
if ($attachments) {
$which = 'attach';
foreach ( $attachments as $attachment_id => $attachment ) {
 $thumb = wp_get_attachment_image( $attachment_id, 'thumbnail', true );
}
}

?
