<p>By default, WooCommerce will only show thumbnails for categories if the category has a thumbnail set.</p>
<p>This plugin changes this behaviour so that WooCommerce will hunt for a product thumbnail in the category being displayed, and use that instead.</p>
<p>Upon activation, the plugin will configure itself with the basic settings. Any categories that you have on your WooCommerce store that do not have a thumbnail set will then start displaying any available product thumbnails inside the category.</p>
<p>There are a number of options, these can be found in WooCommerce -> Settings -> Products -> Auto Category Thumbnails.</p>
<ul>
<li>
<p>Thumbnail Size sets the image size that the plugin should use when displaying the thumbnails. Defaults to shop_thumbail, but shop_catalog may be a better option for some themes.</p>
</li>
<li>
<p>Go into Child Categories makes the plugin look in child categories too, useful if you have products buried in quite a deep category structure.</p>
</li>
<li>
<p>Random Thumbnail tells the plugin to pick a random product thumbnail from those it finds every time the page loads – otherwise it always uses the first one it finds.</p>
</li>
<li>
<p>Use Transients tells the plugin to save the thumbnail it picks for a category as a transient in WordPress, so that it won’t have to do it again while the transient is still active. This can hugely increase performance on sites with many categories, so is enabled by default.</p>
</li>
<li>
<p>Transient Expiry is the length of time each transient is active for before the site picks another thumbnail for the category. By default it is set to 1 day.</p>
</li>
<li>
<p>Custom Transient Expiry can be used to define your own transient expiry period (in seconds) if none of the pre-defined options are suitable.</p>
</li>
<li>
<p>Exclude Thumbnail IDs accepts a comma-separated list of attachment IDs from the WordPress Media Library. The plugin will never use any thumbnail with one of these IDs for a category.</p>
</li>
</ul>

<p>The Selective Thumbnail Regenerator plugin provides a convenient way to regenerate image thumbnails for WordPress media libraries. Unlike other thumbnail regeneration plugins that process the entire library, this plugin allows you to selectively regenerate thumbnails for images uploaded during a specific year and month.</p>
<h4>Key Features</h4>
<ul>
<li><strong>Date-based Selection</strong>: Choose a specific year and month to limit which thumbnails are regenerated</li>
<li><strong>Progress Tracking</strong>: Visual progress bar shows the status of the regeneration process</li>
<li><strong>User-friendly Interface</strong>: Simple dropdown menu interface for date selection</li>
<li><strong>Resource-friendly</strong>: Built-in delay between each regeneration to prevent server overload</li>
<li><strong>Real-time Updates</strong>: Status messages show the current progress and any errors</li>
</ul>
<h3>Usage</h3>
<ol>
<li>In your WordPress admin panel, navigate to Tools > Selective Thumbnail Regenerator.</li>
<li>Select the year and optionally the month for which you want to regenerate thumbnails.</li>
<li>Click “Check Number of Images” to see how many images will be processed.</li>
<li>Click “Regenerate Thumbnails” to start the regeneration process.</li>
<li>Wait for the process to complete – you’ll see a progress bar and status updates.</li>
</ol>
<h3>Troubleshooting</h3>
<h4>Error: “No images found for the selected period”</h4>
<p>This means there are no images in your media library that were uploaded during the selected year and month. Try selecting a different time period.</p>
<h4>The regeneration process is slow</h4>
<p>This is normal behavior. The plugin deliberately adds a 1-second delay between processing each image to prevent server overload. This might make the process seem slow, but it ensures stability.</p>
<h4>The process stops with an error message</h4>
<p>If you encounter an error during regeneration, check your server’s PHP error logs for more details. Common issues include memory limits, timeout settings, or file permission problems.</p>
