I got it with this:
function dhvc_woo_product_page_acf_field_custom($value, $field){ if(!empty($value)) return '<img src="'.$value.'" />'; return $value; } add_filter('dhvc_woo_product_page_acf_field', 'dhvc_woo_product_page_acf_field_custom',10,2);
and changing in ACF to image_url instead of image_object in field.
