'WordPress: Images classified as unattached but they are uploaded to posts
In WordPress, when an image is assigned as a featured image to a post, and then that post is deleted, it becomes an unattached image. It remains unattached even if it's used again in a new post.
This is problematic in my site's workflow. I wrote a script to remove unattached images (to save server space), but it gets rid of images that technically are uploaded to posts, but listed as unattached.
Is there a way to programmatically loop through all unattached media and assign their post_parent to the post they are actually uploaded to? That way they would no longer appear to be unattached.
