The #return section gives keys, but the function just returns indexes. We should make it clearer what is returned by this function. And some description or a link to explain is_intermediate
```
array{
	[0] => url,
	[1] => width</em>
	[2] => height</em>
	[4] => is_intermediate
}
```

Change Icon Directory
WordPress can use media icons to represent attachment files on your blog and in the Admin interface, if those icons are available.
For images, it returns the thumbnail. For other media types, it looks for image files named by media type (e.g., audio.jpg) in the directory wp-includes/images/crystal/.

This example shows how you can change this directory to a folder called “images” in your theme: wp-content/themes/yourtheme/images. Create the folder and put “media type images” in there. To tell WordPress the directory has changed, put this in the current theme’s functions.php file:
```
add_filter( 'icon_dir', 'wpdocs_theme_icon_directory' );
add_filter( 'icon_dir_uri', 'wpdocs_theme_icon_uri' );

/*
 * Return my desired icon directory
 */
function wpdocs_theme_icon_directory( $icon_dir ) {
	return get_stylesheet_directory() . '/images';
}

/*
 * Return my desired icon URI
 */
function wpdocs_theme_icon_uri( $icon_dir ) {
	return get_stylesheet_directory_uri() . '/images'; 
}
```

Retrieve the post thumbnail url sized as 220 if thumbnail exists.

$args = array( 'post_type' => 'post', 'post_status' => 'publish', 'posts_per_page' => 5, 'numberposts' => 5 );

$posts = get_posts( $args );

foreach($posts as $post) {
	$thumbnail_url = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), array('220','220'), true );
	$thumbnail_url = $thumbnail_url[0];
	echo ( !empty($thumbnail_url) ) ? $thumbnail_url : 'No thumb!';

A couple of notes on this page mention getting the first image in a post based on get_children. Unfortunately, that won’t work if you’re using the Gutenberg editor. To get the first image from a Gutenberg-based post, you need to parse the blocks. Here’s a function that will return the ID of the first image in a post, or null if there is none.
```
function first_image_in_blocks( $id ) {
    $post = get_post( $id );
    $blocks = parse_blocks( $post->post_content );

    // Get all blocks that have a core/image blockName
    $images = array_filter( $blocks, function( $block ) {
        return 'core/image' === $block['blockName'];
    } );

    // If there are any images, get the id from the first image, otherwise
    // return null
    return count( $images ) > 0 ? $images[0]['attrs']['id'] : null;
}
```

Here is my code to create custom gallery from post attachment only (I use it in ‘singl.php‘ for specified category)

<!-- begin gallery -->
<?php  if  ( get_the_category()[0]->slug == 'gallery' )  {     ?>
<div class="gallery" id ='lightgallery' >
<?php $attachments = get_posts( array(  'post_type'  => 'attachment', 'post_parent' => $post->ID ) );
if ( $attachments ) {
foreach ( $attachments as $post ) {
echo '<a href="'.wp_get_attachment_image_src( $post->ID, 'full' )[0].'">'  ;
echo  '<img  src="'.wp_get_attachment_image_src( $post->ID )[0].'"  >  </a>';  
 }
 wp_reset_postdata();
 }  ?>
</div>
<?php   }    ?> 
<!-- End gallery -->
