How to delete these attributes? Something like this but for [gallery] output.

How to delete these attributes? Something like this but for [gallery] output.
I can think of a couple of options:
Create a new shortcode, e.g. my_gallery. You can copy the code in
wp-includes/media.php
. Look for the code staring with
add_shortcode('gallery', 'gallery_shortcode');
and then the actual
function. Rename / modify as needed. The actual img link is within
the $link
variable
Use something like this (untested), which should work but might strip-out all width/height from any link.

add_filter('wp_get_attachment_link', 'remove_img_width_height', 10, 1);
function remove_img_width_height($html) {
$html = preg_replace( '/(width|height)=\"\d*\"\s/', "", $html );
return $html;
}
if you set image size in function.php as a "gallery"
add_image_size( 'gallery', 200, 120, true );
you can remove width and height of specific image size such as "gallery":
add_filter('wp_get_attachment_link', 'remove_img_width_height', 10, 4);
function remove_img_width_height( $html, $post_id, $post_image_id,$post_thumbnail) {
if ($post_thumbnail=='gallery'){
$html = preg_replace( '/(width|height)=\"\d*\"\s/', "", $html );
}
return $html;
}
