Allow Image HTML tags in WordPress Comments

By hooking into the wp_kses_allowed_html filter, you have full control over what HTML is allowed to be displayed in post and comment content.

Unfortunately the $context provided by the filter’s 2nd parameter does not describe the difference between a post and a comment, so we have to alter them all equally.

<?php
add_filter( 'wp_kses_allowed_html', array( $this, 'my_kses_allowed_html_hook' ), 20, 2 );
function my_kses_allowed_html_hook( $tags, $context = null ){
if ( 'post' == $context && ! isset( $tags['img'] ) ) {
$tags['img'] = array(
'src' => 1,
'height' => 1,
'width' => 1,
'alt' => 1,
'title' => 1
);
}

return $tags;
}
