I just replied but it seems to have vanished.

Thanks for your reply, however after a few attempts I’m stuck and not sure where to place the foreach loop you mention.

I have a galley (I’ve stripped back the code here)

<?php //Gallery images

$images = get_field('image_gallery');
$size = 'full';

if( $images ): ?>
	<?php foreach( $images as $image ): ?>
		<img class="grid-entry" src="<?php echo $image['url'];?>" alt="<?php echo $image['alt']; ?>" />
	<?php endforeach; ?>
<?php endif; ?>

Could I weave the the update_field into that foreach loop?
Or does it need to be somewhere else?

e.g.

<?php //Gallery images

$images = get_field('image_gallery');
$size = 'full'; //

$count = (int) get_field('field_59b6acbe2a8d2');

if( $images ): ?>
	<?php foreach( $images as $image ): 
		// increase
		$count++;
		// update
		update_field('field_59b6acbe2a8d2', $count); ?>
		<img class="grid-entry" src="<?php echo $image['url'];?>" alt="<?php echo $image['alt']; ?>" />
	<?php endforeach; ?>
<?php endif; ?>

Once that is working, does it only take a refresh of the page for it to update the images?

Many thanks
