How to Remove Width and Height Attributes From Inserted Images.
When we upload an image through the WordPress media uploader and then insert it into the tinyMCE editor, it comes with height & width attributes. But if you want to remove the insert action from adding these attributes, you can add this code to you functions.php file or a functionality plugin of your own making:
[php]
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;
}
[/php]
