 Currently, in order to display an attachment image without width and
 height attributes you must do something like this:

 {{{
 $image = wp_get_attachment_image_src( $attachment_id, 'my-image-size' );
 $alt = get_post_meta( $attachment->ID, '_wp_attachment_image_alt', true );
 echo '<img src="' . $image[0] . '" alt="' . $alt . '" />';
 }}}

 This feels very clumsy and it only works on a call by call basis. To
 remove it via filters requires a regex to manipulate the full IMG tag as a
 string.  What this patch does is add 'width' and 'height' attributes to
 the $default_attr array within the wp_get_attachment_image function so
 that they can be directly modified via the
 'wp_get_attachment_image_attributes' filter.  This makes it very easy to
 remove or modify the width and height attributes without any regex
 knowledge.

 Here's an example with the new version that would remove all width and
 height attributes to any attachment images:


 {{{
 function remove_image_dimensions( $attr ) {
         unset( $attr['width'] );
         unset( $attr['height'] );
         return $attr;
 }

 add_filter( 'wp_get_attachment_image_attributes',
 'remove_image_dimensions', 10 );
 }}}
