complete post

Hi prethon. I already answered that question in your other post here:

To hide the image you could add this to a child theme style.css file or a plugin like Simple CSS or Simple Custom CSS:

.post-thumbnail {
    display: none;
}

this post is complete on the page, completing where had the thumbnail ?

Look at the site please delete the thumbnail , but the post did not complete the page

The code I posted above will hide the post featured image. Your images are part of your post content. If you want to hide the content images use this:

.post .entry.excerpt img {
    display: none;
}
