You are welcome.

I was actually looking for some simple SQL command or something (like a plugin to bulk remove featured images from selected posts) to remove the featured images on the database end itself.

As @mor10 pointed out, that it is an issue with most themes providing featured image option. Thus solving it at database end would solve it for all the themes. Also, it makes it easier later when the theme patches are released.

Thanks.

Thanks @mor10, it does make sense. Will give creating child theme a try.

@mor10: Thanks for the workaround and the explanation about the internals of Twenty Eleven. That sounds fair enough.

Any simple tips to remove featured image (without deleting the image from post) for all the posts?

Steps for reproduction:

Upload image by selecting “Add media”
Click “Use as featured image”
Click “Insert into post”
Save and publish

From one of my test blogs: https://codewordz.com/android/fonedanz-cinemagraph-alternative-for-android/

The GIF (featured image) is shown twice on top (and also shown twice on the index).
