需求：将图片作品集跳转行为改为PrettyPhoto Lightbox弹窗展示

Hey there! Let's get that lightbox popup working for your image gallery. Since your theme doesn't have a built-in option for this, we can implement it using the prettyPhoto plugin just like the demo you referenced. Here's a step-by-step guide:

First, we need to load the necessary files for prettyPhoto to work:

• If your theme doesn't already include jQuery (most do), add this snippet to your theme's header.php right before the closing </head> tag:

  <script src="https://code.jquery.com/jquery-3.6.4.min.js"></script>
  

• Next, add the prettyPhoto stylesheet and script. You can host these files locally on your server or use a CDN. Add these lines right after the jQuery script:

  <link rel="stylesheet" href="path/to/prettyPhoto.css" type="text/css" media="screen" />
  <script src="path/to/jquery.prettyPhoto.js" type="text/javascript"></script>
  

  Pro tip: Replace path/to/ with the actual file path if hosting locally, or use a public CDN link for quicker setup.

Right now, your images are wrapped in links that jump to other pages. We need to tweak those links to target the full-size image and add prettyPhoto-specific attributes:

• For each image in your gallery, update the link tag to look like this:

  <a href="full-size-image-url.jpg" rel="prettyPhoto[gallery]" title="Your Image Caption">
    <img src="thumbnail-image-url.jpg" alt="Image Description" />
  </a>
  

  • rel="prettyPhoto[gallery]": Groups all images into one gallery, so visitors can navigate between them with next/prev buttons.
  • href: Must point to the full-resolution version of your image (not a page URL).
  • title: Optional, adds a caption below the image in the lightbox.

Add this script to your theme's footer.php right before the closing </body> tag to activate the lightbox:

<script type="text/javascript">
  $(document).ready(function(){
    $("a[rel^='prettyPhoto']").prettyPhoto({
      // Customize these settings to match your site's style
      theme: 'light_square', // Options: light_rounded, dark_rounded, light_square, dark_square, facebook
      autoplay_slideshow: false,
      social_tools: false // Hide social buttons if you don't need them
    });
  });
</script>

• Clear your site and browser cache, then click any image in your gallery—it should now open in a prettyPhoto lightbox instead of navigating away.
• If it's not working, check these common fixes:
  • Confirm jQuery loads before the prettyPhoto script.
  • Double-check that the paths to prettyPhoto's CSS and JS files are correct.
  • Make sure all image links have the rel="prettyPhoto[gallery]" attribute and point to valid image files.
