Hi @dadra
You could create a select field and populate the choices with ‘thumbnail, medium, large, full, custom-size, etc’.
Then in your code, you can load in the image like so:
<?php
$image = get_field('image');
$size = get_field('size');
echo $image['sizes'][ $size ];
?>
The above example expects your image field to return an array of data, but you could change this to ID and modify the code as per the docs.
Thanks
