Here’s the new code that don’t double the image. But there’S still the Vimeo Embed bug with Chrome…
<?php $images = get_field('gallery');
if( $images ): ?>
<?php foreach( $images as $image ): ?>
<div class="project_image twocolumn">
<?php if( $image['description'] ): ?>
<div class="vimeo"><?php echo $image['description']; ?></div>
<p class="caption"><?php echo $image['caption']; ?></p>
<?php endif; ?>
<?php if( !$image['description'] ): ?>
<a href="<?php echo $image['url']; ?>"><img src="<?php echo $image['sizes']['large']; ?>" /></a>
<p class="caption"><?php echo $image['caption']; ?></p>
<?php endif; ?>
</div>
<?php endforeach; ?>
<?php endif; ?>
