I'm sorry if this is too noob of a question, but when I upload an image and set it as the featured image then later remove it (as featured image), the media list still shows it's "Attached to" the post I removed it as featured image from. Any clue?
More importantly, how do I then make it so that when I remove the featured image, it will be "Unattached"? Any hook I can attach to or the like?
Thanks so much.
