This php code is working and creates 'previous' and 'next' button style links for a photo gallery.
<a href="<?php the_permalink(); if($i> 0) {echo $i-1;} elseif($i!=0) {echo $i;} ?>" class="btn-1 btn-align-left btn-previous"><i>&nbsp;</i><b><span><?php printf ( __( 'Previous photo' , 'rayoflight' ));?></span></b><u>&nbsp;</u></a>
<a href="<?php the_permalink(); if($i+1 < $count) {echo $i + 1;} elseif($i!=0) {echo $i;} ?>" class="btn-1 btn-align-left btn-next"><i>&nbsp;</i><b><span><?php printf ( __( 'Next photo' , 'rayoflight' ));?></span></b><u>&nbsp;</u></a>

But if I have a single image (count would = 0) the buttons still show up. The links don't jump anywhere but the buttons are still showing. How can I change the code so the buttons do not appear if there is no previous or next image?

<?php if(count > 0) { ?>
<a href="<?php the_permalink(); if($i> 0) {echo $i-1;} elseif($i!=0) {echo $i;} ?>" class="btn-1 btn-align-left btn-previous"><i>&nbsp;</i><b><span><?php printf ( __( 'Previous photo' , 'rayoflight' ));?></span></b><u>&nbsp;</u></a>
<a href="<?php the_permalink(); if($i+1 < $count) {echo $i + 1;} elseif($i!=0) {echo $i;} ?>" class="btn-1 btn-align-left btn-next"><i>&nbsp;</i><b><span><?php printf ( __( 'Next photo' , 'rayoflight' ));?></span></b><u>&nbsp;</u></a>
<?php } ?>

I ended up using this:
<?php if($i > 0) { ?>
<a href="<?php the_permalink(); if($i> 0) {echo $i-1;} elseif($i!=0) {echo $i;} ?>" class="btn-1 btn-align-left btn-previous"><i>&nbsp;</i><b><span><?php printf ( __( 'Previous photo' , 'rayoflight' ));?></span></b><u>&nbsp;</u></a>
<?php } ?>

<?php if($count > 1) { ?>
<a href="<?php the_permalink(); if($i+1 < $count) {echo $i + 1;} elseif($i!=0) {echo $i;} ?>" class="btn-1 btn-align-left btn-next"><i>&nbsp;</i><b><span><?php printf ( __( 'Next photo' , 'rayoflight' ));?></span></b><u>&nbsp;</u></a>
<?php } ?>
