Hide in-content images

You can add this snippet to your index file:
https://www.isitwp.com/remove-all-images-from-the_content-in-a-post/

I tried this above, but couldn’t get it to work.

I’ve also tried

function remove_images( $content ) {
   $postOutput = preg_replace('/<img[^>]+./','', $content);
   return $postOutput;
}
add_filter( 'the_content', 'remove_images', 100 );

But image captions still shows

Use the function that works for the images, then just add this to your css,
Admin –> Customizer –> Additional CSS:

.wp-block-image figcaption {
    color: #555;
    font-size: 13px;
    text-align: center;
    display: none;
}

That CSS didn’t work for me, thanks for trying.

Then just get the selector from your html that is being used to output the caption, and replace the selector in the css.
I’m running Gutenburg on WordPress 5.8.1

How can I include the removal of alt text as well as captions?

The alt text is included in the tag and should not display.

If you want more specific support, provide a url or a screenshot of your markup.

These captions still show above

.wp-caption .wp-caption-text {
    margin: .8075em 0;
    display: none;
}

Thank you very much, you are a star!
