title: Download multiple images in zip in Wordpress
body: <p>I am working on my personal wordpress site that distribute images.</p>
  
  <p>In single post page, I registered several images via ACF(Advanced Custom Fields) and I know how to get image path/filename through <code>get_field</code> ACF function.</p>
  
  <p>I just googled then found this page, but how can I apply this technique to wordpress site?
