Batch processing of the height and width limit of pictures uploaded by WordPress

By default, WordPress images will have a set size when we send them. But sometimes we want to change the width and height. We can remove them in batches.

 // By laozuo.org      add_filter( 'post_thumbnail_html', 'remove_width_attribute', 10 ); add_filter( 'image_send_to_editor', 'remove_width_attribute', 10 ); function remove_width_attribute( $html ) { $html = preg_replace( '/(width|height)="\d*"\s/', "", $html ); return $html; }
