in this post, I'll show you how to remove image attributes(width,height,typeof) in drupal 8.
for removing image attributes, I'll use template_preprocess_image() like this:
<?php
/**
* @param $variables
*/
function mytheme_preprocess_image(&$variables)
{
if (isset($variables['attributes']['width'])) {
unset($variables['attributes']['width']);
}
if (isset($variables['attributes']['height'])) {
unset($variables['attributes']['height']);
}
if (isset($variables['attributes']['typeof'])) {
unset($variables['attributes']['typeof']);
}
}
