How do i check if next picture exists or not

Answer 1

<div id="full">
  <?php $i=0; foreach ($array as $image): ?>

      <?php if(file_exists($image['image'])): ?>

      <div id="image<?php echo $i;?>" 
         class="img bg-img<?php echo $i+1;?>">
      <img src="<?php echo $image['image']; ?>" ></img>
      </div>

    <?php else: break; ?>

  <?php $i++; endforeach ?>         
</div>

This will check if the image exists, and echo it if does. If not it will break out of the loop (essentially cancelling it. Depending on the data you may want to use a continue in place of break
