When I upload an image to a page, WordPress seems to store the page as that image’s “parent”. When I look in the Media Library, this is the “attached to” field. How can I change this value (i.e. reassign an image to another page)?
Of course, you know you can add the image to as many posts/pages as you want by selecting the Media Library, but I don’t see an option in the WP admin to change the post/page the image is attached to…you would probably need to do that directly in the database.
