Not an issue: wordpress responsive image sizes about acf-image-crop HOT 1 OPEN

you always can get the different sizes, the only limitation is that the crop images must published to the library and not only to the post.

this is my code I actually use:
`
// http://aaronrutley.com/responsive-images-in-wordpress-with-acf/
// and additional infos from here: https://rudrastyh.com/wordpress/responsive-images.html

// Responsive Image Helper Function
// @param string $image_id the id of the image (from ACF or similar)
// @param string $image_size the size of the default src size
// @param string $image_max_size the max withe of the images used in this function and custom_max_srcset_image_width funtion !!!
// @param string $image_sizes_attribute the definition with of the sizes attribute (simple 100vw or with media queries

function custom_responsive_image($image_id,$image_size,$image_max_size,$image_sizes_attribute){
// check the image ID is not blank
if($image_id != '') {

	// set the default src image size
	$image_src = wp_get_attachment_image_url( $image_id, $image_size );

	// set the srcset with various image sizes
	$image_srcset = wp_get_attachment_image_srcset( $image_id, $image_max_size );
	
	// generate the markup for the responsive image
	if ($image_srcset) {
		return 'src="'.$image_src.'" srcset="'.$image_srcset.'" sizes="'.$image_sizes_attribute.'"';
	} else {			
		return 'src="'.$image_src . '" ';
	}
	
}

}

add_filter( 'max_srcset_image_width', 'custom_max_srcset_image_width', 10 , 2 );

function custom_max_srcset_image_width() {
return '2560'; // set the max images size as max fot the responive image generating
// return $image_max_size; // set the max images size as max fot the responive image generating
}
`

`
$image_alt = $image_object['alt'];
// Responsive Image Helper Function
// @param string $image_id the id of the image (from ACF or similar)
// @param string $image_size the size of the default src size
// @param string $image_max_size the max withe of the images used in this function and custom_max_srcset_image_width funtion !!!
// @param string $image_sizes_attribute the definition with of the sizes attribute (simple 100vw or with media queries
$image_id = $image_object['id'];

				if ($grid == 'rectangle') {
					$image_size = 'responsive_480';
					$image_max_size = 'responsive_1680';
					$image_sizes_attribute = '(max-width: 48em)100vw, (min-width: 48em)50vw, 50vw';
				 } elseif ($grid == 'square') {	
					$image_size = 'responsive_480';
					$image_max_size = 'responsive_1024';
					$image_sizes_attribute = '(max-width: 48em)100vw, (min-width: 48em)33vw,(min-width: 64em)33vw, 33vw';
				}
				
				if (function_exists('custom_responsive_image') && $image_id && $image_size && $image_max_size && $image_sizes_attribute) {
					$image_src = custom_responsive_image( $image_id,$image_size,$image_max_size,$image_sizes_attribute ); // responisve image http://aaronrutley.com/responsive-images-in-wordpress-with-acf/
				}
