I found this great solution: Stop wordpress from hardcoding img width and height attributes

But I was wondering if I could do it only in one specific case and not in all the site because it messes up other stuff. This would be the case:

<?php echo wp_get_attachment_image($attachment->ID, 'six', false, $default_attr); ?>

Removing only height but not width in all the site would also work.

    Can you explain why you want to do this? Understanding your need may open up other solutions. – Steve Nov 1 '12 at 23:17

You can also get the data for width and hight of a image.

$src = wp_get_attachment_image_src( $attachment_id, 'full' );
var_dump($src);

the var_dump output like this:

array
  0 => string 'http://example.com/wp-content/uploads/2009/08/DSC00261.JPG' (length=63)
  1 => int 1632
  2 => int 1224
  3 => boolean false

The results mean:

$src[0] => url
$src[1] => width
$src[2] => height
$src[3] => icon

This worked for me.

function remove_width_and_height_attribute( $html ) {
   return preg_replace( '/(height|width)="\d*"\s/', "", $html );
}

and then change

wp_get_attachment_image_src( $attachment_id, 'full' );

to

remove_width_and_height_attribute(wp_get_attachment_image_src( $attachment_id, 'full' ));
  • Instead of removing the width and height, you could also make them more useful by making a proper style attribute for them. Even though that's not what the OP asked, it will make the page less "jumpy" if there are lots of images to load: return preg_replace('/ width="(\d*)" height="(\d*)" /', ' style="width:$1px;height:$2px;" ', $html); – Sphinxxx Jul 18 '15 at 2:25
  • inline style is generally considered a bad idea. Both for maintenance sake and speed. – S.. Jul 18 '15 at 7:14

One specific case and not in all the site.

Fx. If you want to remove width="400" from WordPress a HTML output function, you could do this:

Somewhere in a file:

ob_start(); // Start buf
wp_get_attachment_image($imageID, 'full', false); //'full' = size
$htmlString = ob_get_clean(); // output to variable
echo preg_replace('/width="\d*"/','',$variable); // Remove width attribute and whatever digit inside.

Maybe not the most elegant solution, but it gets the job done.
