This code will only show an image if one is available:
<?php $image = get_field('image');
if( !empty( $image ) ): ?>
<img src="<?php echo esc_url($image['url']); ?>" alt="<?php echo esc_attr($image['alt']); ?>" />
<?php endif; ?>
So to extend this:
<style>
.hide-me {
display: none;
}
<?php $image = get_field('image');
if( !empty( $image ) ): ?>
<div class="hide-me">
<img src="<?php echo esc_url($image['url']); ?>" alt="<?php echo esc_attr($image['alt']); ?>" />
</div>
<?php endif; ?>
If no image is set, the whole div with the class hide-me will not be shown
