Wordpress滑块拇指，如何限制前6与数组？

Question

我试图将下面的代码所显示的拇指限制在滑块中的前6项上，但我无法让它工作。有人知道我在找什么吗？

<ul class="pictures-2">
<?php
foreach( $properties_images as $prop_image_id=>$prop_image_meta ){
$slider_thumb = wp_get_attachment_image_src($prop_image_id,'property-thumb-image');
echo '<li>';
echo '<img src="'.$slider_thumb[0].'" alt="'.$prop_image_meta['title'].'" />';
echo '</li>';
}
?>
</ul>

<ul class="pictures-2">
    <?php
    $i=0;
    foreach( $properties_images as $prop_image_id=>$prop_image_meta ){
        $i++;
        if ($i <= 6) {
            $slider_thumb = wp_get_attachment_image_src($prop_image_id,'property-thumb-image');
            echo '<li>';
            echo '<img src="'.$slider_thumb[0].'" alt="'.$prop_image_meta['title'].'" />';
            echo '</li>';
        } else {
            //Do Nothing
        }
    }
?>
</ul>
