<p>Image Sizes on Demand generates sizes of an image at the moment they are requested. It tries to generate the new size<br />
from the original image, if it exists. This means you don’t need to regnerate all your images if you add new iamge<br />
sizes.</p>

<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>
