<p><strong>Petro SEO Images to WebP</strong> converts your existing JPEG and PNG attachments to WebP in bulk, then serves them on the front-end through the standard <code><picture></code> element with a full responsive <code>srcset</code>. The original files stay untouched on disk, so reverting is as simple as flipping a switch.</p>
<p>Designed to be small, dependency-free and predictable. No external services, no images uploaded anywhere, no opaque queue.</p>
<h4>What it does</h4>
<ul>
<li>Converts every registered image size (full + thumbnails) to <code>.webp</code> next to the original (e.g. <code>photo.jpg</code> <span aria-hidden="true" class="wp-exclude-emoji">→</span> <code>photo.jpg.webp</code>).</li>
<li>Wraps <code><img></code> tags from <code>wp_get_attachment_image()</code> and <code>the_content</code> in <code><picture><source type="image/webp">…</picture></code>, preserving full <code>srcset</code> and <code>sizes</code>.</li>
<li>Skips images automatically if a previous run failed because of filesystem permissions, so you can retry on demand without reprocessing the whole library.</li>
<li>Ramps the WebP quality down (75 <span aria-hidden="true" class="wp-exclude-emoji">→</span> 60 <span aria-hidden="true" class="wp-exclude-emoji">→</span> 45 <span aria-hidden="true" class="wp-exclude-emoji">→</span> 40) when the encoded file ends up larger than the original, so you never ship a “WebP” that is heavier than the JPEG.</li>
<li>Idempotent: re-running the bulk job only touches new or updated images.</li>
</ul>
<h4>What it does NOT do</h4>
<ul>
<li>It does not delete or modify your original JPG/PNG files.</li>
<li>It does not require Imagick or a specific image library beyond what WordPress already uses (<code>wp_get_image_editor()</code>).</li>
<li>It does not phone home, register endpoints, or load remote scripts.</li>
</ul>
<h4>Privacy</h4>
<p>The plugin processes images locally using WordPress’s built-in image editor. No data is sent to third-party services.</p>

<p>Attachments allows you to simply append any number of items from your WordPress Media Library to Posts, Pages, and Custom Post Types.</p>
<h4>Associate Media items with posts</h4>
<p>The idea behind Attachments is to give developers the ability to directly associate Media items with any post. This is accomplished by adding a meta box to post edit screens as determined by the developer. Once Media items have been associated with a post, you’re able to retrieve those Attachments and include them directly within your template files using any specific markup you wish.</p>
<h4>Integrate Attachments within your theme with fine grained control</h4>
<p><strong>Attachments does not automatically integrate itself with your theme.</strong> Since the idea behind Attachments is to allow integration of Media within posts using developer-crafted, unique markup, <em>it’s up to you to integrate with your theme</em>. The most basic integration includes editing the <a href="https://codex.wordpress.org/Template_Hierarchy" rel="nofollow ugc">appropriate template file</a> and adding your call(s) to Attachments. For example, if you have set up Attachments to be used with your Posts entries, edit <code>single.php</code> to include the following within The Loop:</p>
<pre><code><?php $attachments = new Attachments( 'attachments' ); /* pass the instance name */ ?>
<?php if( $attachments->exist() ) : ?>
  <h3>Attachments</h3>
  <p>Total Attachments: <?php echo $attachments->total(); ?></p>
  <ul>
    <?php while( $attachments->get() ) : ?>
      <li>
        ID: <?php echo $attachments->id(); ?><br />
        Type: <?php echo $attachments->type(); ?><br />
        Subtype: <?php echo $attachments->subtype(); ?><br />
        URL: <?php echo $attachments->url(); ?><br />
        Image: <?php echo $attachments->image( 'thumbnail' ); ?><br />
        Source: <?php echo $attachments->src( 'full' ); ?><br />
        Size: <?php echo $attachments->filesize(); ?><br />
        Title Field: <?php echo $attachments->field( 'title' ); ?><br />
        Caption Field: <?php echo $attachments->field( 'caption' ); ?>
      </li>
    <?php endwhile; ?>
  </ul>
<?php endif; ?>
</code></pre>
<p>That snippet will request all of the existing Attachments defined for the current Post within The Loop, and retrieve each itemized property for that Attachment. Using the provided details you’re able to integrate the attached Media items in any way you please.</p>
