Deleting images from gallery remain as attachment

Question

Process creating a gallery:

1. I create a post with post format gallery
2. I add images from "Add media", note I don't use "Create gallery" but insert pictures into the post
3. update

then I have a php side

$attachments = get_children( array( 'post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $atts['order'], 'orderby' => $atts['orderby'] ) );

this code comes from gallery_shortcode function in media.php.

it works perfect, but when I try to delete image from post, no matter how I try it it is still there. I have not tried this but obviously deleting image permanently from media would work, but I want this images to still remain there.

how to delete them as attachments for this images from post editor?

Answer 1

A quick way to detach images is to select Media Library from the menu, Find the images you want to detach, and click the Detach link in the Uploaded to column. This will remove the value saved in post_parent for the attachment.
