WordPress automatically adds the width and height attributes to [gallery] shortcode images.
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 withadd_shortcode('gallery', 'gallery_shortcode');and then the actual function. Rename / modify as needed. The actual img link is within the$linkvariableUse something like this (untested), which should work but might strip-out all width/height from any link.
_
add_filter('wp_get_attachment_link', 'remove_img_width_height', 10, 1);
function remove_img_width_height($html) {
$html = preg_replace( '/(width|height)=\"\d*\"\s/', "", $html );
return $html;
}

@TohidGolkar has the right idea below. Both of the options provided are terrible. Rewriting the core (1st solution), and removing widths/heights across all attachment links is no better. – Dan Jan 29 '13 at 6:33

I wasn't suggesting to rewrite the core, but just to adapt it (copy the code and re-use it as you see fit) and create your own version of it. As for the 2nd option - yeah, it's not great and I explained how it might alter all image links. I totally agree that the version of @TohidGolkar looks much better since it's more fine-grained. – Yoav Aner Jan 29 '13 at 10:22

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;
}
