 * Hi, after I updated wordpress to 5.5 the following code doesn’t work anymore.
 *     ```
         function remove_width_attribute($html)
       {
           $html = preg_replace('/(width|height)="\d*"\s/', "", $html);
           return $html;
       }
   
       add_filter('post_thumbnail_html', 'remove_width_attribute', 10);
       add_filter('image_send_to_editor', 'remove_width_attribute', 10);
       ```
   
 * Actually in the Editor I don’t see width and height …. but when I open the blog
   post now, the image / figure contains width and height and that is not what I
   am expecting, can someone help me out?
    Thanks

 * The block editor does not fire “image_send_to_editor”. It’s only applied in the
   classic editor. “post_thumbnail_html” should still work AFAIK since featured 
   image output is independent from editor content. I’m not sure if there is an 
   equivalent to “image_send_to_editor”, the block editor works very differently
   than classic editor.
 * You might try removing the offending attributes from the data filtered by “wp_kses_allowed_html”.
   Untested. You can always filter “the_content”, but doing preg_replace() on all
   content is not very efficient. You’re better off doing so when the post is saved
   through “wp_insert_post_data” filter.
 * Out of curiosity, how are the attributes a problem? CSS overrides the attribute
   values, they are essentially a legacy feature AFAIK.

 * Hi [@bcworkz](https://wordpress.org/support/users/bcworkz/),
 * It was stretching the images … but you are right, I will fix it with css.
 * Thank you

 * Hi!
 * I fix this stretching issue by adding following lines at the beginning of my 
   css file
 *     ```
       figure > img {
       	width: auto;
       	height: auto;
       }
       ```
