   This little line of code saved me a lot of hassle. Thanks for that! I had imported about 50 articles and WordPress was saying each one had a featured image when it did not have one.

   I already know why it was doing that…long story…however, how am I to remove the featured image when there is nothing to remove?? Just paste these lines of code into the functions.php file like the article says and voila! All ghost images removed

   wpbeginner makes me SO happy

   Deleting all the server images assigned to the thumbnails is relatively simple, now, how to condition to delete all uploads not used by the server as featured images? This should be the most interesting, clean the images not used by the system, in order to polish the machine resources deleting junk images, not used.

    Is there anyway to undo this? I didnt realise it would remove thumbnail images as well. I have tried restoring the thumbnails but it is not working. Thanks

    #1. Are we 100% positive that the current code does NOT delete any images from my media folder? And simply “unset” them from featured image?

    #2. You mention “However, the query can be modify to exclude certain post types.” Can you share the code I would use to avoid a category with ID=25?

    Thank you so much,
    Mike

    After delete my related images my images from homepage desappeared, but when I go to post details it appears normally. Before run the script, the homepage used the images from inside the post and not from related images, so I really don’t know why they desappeared from my homepage. Do you have any idea why this happened?

      You will have to delete images from media library.

        Wish someone would have made a plugin like that because deleting images from 100-200 posts is very time consuming… ?? if any plugin of that kind comes up pls do update it in ur site.. thanks for your reply

    BEWARE

    I used this code yesterday to try to delete the featured images as part of an upgrade to a new Wordpress theme. While it did delete the featured images from posts, it also deleted them from the media library and I think it’s also deleted the original files from the server.

    Having used this code to try and speed thing up, I now find myself having to re-install and re-link over 2,500 images for my site.

      Justin, we tested the code again. It does not delete files from your media library or your server. It just unsets featured images.

        I am facing the same problem. After adding this code, few images are being erased from media library.

        • WPBeginner Support

          Sudip, thank you for notifying us. We have updated the article. Please try the new code instead.

    One should also note that this deletes featured images not just from standard post, but from all posts (including custom post types), correct?

    返信

    • WPBeginner Support

      Yes this is correct. However, the query can be modify to exclude certain post types.

    Wouldn’t it be easier to just run a query on DB directly?

    返信

    • WPBeginner Support

      Yep, and this is exactly what this code is doing.
