Hi,
It should works.
You can also choose Image Object radio box then get the value with get_field_object('image'). It retrives an array with almost anything you need. For example you can get image url like below:
$fields = get_field_object('image');
<img src="<?php echo $fields['value']['url']; ?>" alt="<?php echo $fields['value']['alt']; ?>" />
For seeing the whole array use <pre><?php print_r(get_field_object('image'))?></pre> somewhere in the loop.
I hope that helps,
