On your review page, set the post object field for the manufacturer to return the id of the manufacturer post.
/*
this would be somewhere in your post loop on review page
set the manufacturer field to return id of manufacturer post object
*/
$mf_post_id = get_field('manufacturer');
if ($mf_post_id) {
/*
$mf_post_id should hold the manufacturer post id where the image
image field is located. Now get the image field from that
manufacturer post
*/
$image = get_field('manufacturer_logo', $mf_post_id)
/*
$image should contain the value returned for the
logo image field on the manufacturer post
*/
}
Hope that explains it better.
