I have created a custom post type with an image gallery upload. Now I am trying to display the gallery on the front end. This is what I have so far that works to display 1 image, but if multiple images are uploaded all the urls get stuck in the src tag. So I’m guessing I should loop through that array and spit out each one separately? Would that be the route to go and if so how can I accomplish this? Any help is appreciated.

<?php if (have_posts()) :  while (have_posts()) : the_post(); ?>

<?php
echo '<img src="'.get_post_meta($post->ID, 'gallery-upload', true).'">';    
?>

<?php endwhile; else: ?>
    <p><?php _e('No posts were found. Sorry!'); ?></p>
<?php endif; ?>

EDIT:

This is what is being returned:

    Looking at the function reference, get_post_meta ordinarily returns an array unless the third argument is set to true. Something like this should work, more or less.

    <?php
foreach(get_post_meta($post->ID, 'gallery-upload') as $meta) {
  foreach(explode(',', $meta) as $src) {
    echo '<img src="'.htmlentities($src).'">';
  }
}
?>

    EDIT: Apparently gallery-upload is stored as comma-separated values. Updated my snippet above to hopefully account for this.
