Hi, I am currently using this code with the Gallery field type:

<?php $images = get_field('photo_gallery','17'); if( $images ): ?>
    <ul>
        <?php foreach( $images as $image ): ?>
            <li>
                <a href="<?php echo $image['url']; ?>" rel="lightbox">
                     <img src="<?php echo $image['sizes']['photo-gallery']; ?>" alt="<?php echo $image['alt']; ?>" />
                </a>
            </li>
        <?php endforeach; ?>
        <div id="clearfloat"></div>
    </ul>
<?php endif; ?>

I need to adjust the coding to make it limit the amount of images and randomize the images. Can you help? Thanks

New code mixed into yours and commented

<?php 
    $images = get_field('photo_gallery','17'); 
    if( $images ):
        shuffle($images); // randomizes the image array
        $max = 10; // set the max here;
        $count = 0; // current count
?>
    <ul>
        <?php 
            foreach( $images as $image ):
                $count++; // increment count
                // if count is greater than limt, stop showing images
                if ($count > $max) {
                    break;
                }
         ?>
            <li>
                <a href="<?php echo $image['url']; ?>" rel="lightbox">
                     <img src="<?php echo $image['sizes']['photo-gallery']; ?>" alt="<?php echo $image['alt']; ?>" />
                </a>
            </li>
        <?php endforeach; ?>
        <div id="clearfloat"></div>
    </ul>
<?php endif; ?>
