Have custom image size appear in Image Block “Resolution” options

[ad_1]

I’ve registered a new image size with `add_image_size` and added a label via `image_size_names_choose` but my image size option does not appear for images placed using the Image Block. What else do I need to do?

Here is where the image option should appear. I only see the WordPress defaults of “Thumbnail,” “Medium,” and “Full.”

add_image_size(‘image-card’, 500, 500, TRUE);
add_filter(‘image_size_names_choose’, ‘custom_sizes’);
function custom_sizes($sizes) {
return array_merge($sizes, [
‘image-card’ => __(‘Image Card’, ‘custom’),
]);
}
