My if/else php not working – help!

Hello.
I’ve got a slideshow on a post page that is working nicely.

However, the client won’t always be able to upload even one image so I want a fallback.

This is my existing code:

<!-- slideshow -->
<?php if( have_rows('news_slideshow') ): ?>
<!-- data-ratio="820/542" -->
<div class="the-slideshow slideshow-news">		
	<div class="fotorama" 
		data-width="100%" 
		data-ratio="820/542" 
		data-minwidth="285" 
		data-loop="true" 
		data-swipe="true" 
		data-click="true"
		data-nav="false"
		data-transition="crossfade"
		data-transitionduration="1500"
		data-autoplay="4000">
		<?php while ( have_rows('news_slideshow') ) : the_row(); ?>
			<?php 
			$slideLarge = get_sub_field('news_slideshow_image');
			$size = 'full'; // (thumbnail, medium, large, full or custom size)
			?>	
			<?php echo wp_get_attachment_image( $slideLarge, $size );  ?>
		<?php endwhile; ?>
	</div>
</div>
<?php endif; ?>	
<!-- end slideshow -->

I tried to modify it to include an else statement so that if no image were uploaded I could display the contents of another field.

This is the code I tried (which failed):

<!-- slideshow -->
<?php if( have_rows('news_slideshow') ): ?>
<!-- data-ratio="820/542" -->
<div class="the-slideshow slideshow-news">		
	<div class="fotorama" 
		data-width="100%" 
		data-ratio="820/542" 
		data-minwidth="285" 
		data-loop="true" 
		data-swipe="true" 
		data-click="true"
		data-nav="false"
		data-transition="crossfade"
		data-transitionduration="1500"
		data-autoplay="4000">
		<?php while ( have_rows('news_slideshow') ) : the_row(); ?>
			<?php 
			$slideLarge = get_sub_field('news_slideshow_image');
			$size = 'full'; // (thumbnail, medium, large, full or custom size)
			?>	
			<?php echo wp_get_attachment_image( $slideLarge, $size );  ?>
		<?php endwhile; ?>
	</div>
</div>

<?php else: ?>
	<?php echo 'Something else' ?>
<?php endif; ?>
<!-- end slideshow -->

Could any one point out where I’m going wrong here?

Thanks!

Just solved it myself! Here’s the answer (might conceivably be of use to someone else):

<!-- slideshow -->
<?php if( have_rows('news_slideshow') ): ?>
<!-- data-ratio="820/542" -->
<div class="the-slideshow slideshow-news">		
	<div class="fotorama" 
		data-width="100%" 
		data-ratio="820/542" 
		data-minwidth="285" 
		data-loop="true" 
		data-swipe="true" 
		data-click="true"
		data-nav="false"
		data-transition="crossfade"
		data-transitionduration="1500"
		data-autoplay="4000">
		<?php while ( have_rows('news_slideshow') ) : the_row(); ?>
			<?php if( !empty(get_sub_field('news_slideshow_image')) ) : ?>
				<?php 
				$slideLarge = get_sub_field('news_slideshow_image');
				$size = 'full'; // (thumbnail, medium, large, full or custom size)
				?>	
				<?php echo wp_get_attachment_image( $slideLarge, $size );  ?>
			
			<?php else: ?>
				<?php echo 'something else'; ?>
			<?php endif; ?>
		<?php endwhile; ?>
	</div>
</div>
<?php endif; ?>
<!-- end slideshow -->
