<h4>Delete thumbnails & resized images from your Media Library</h4>
<ul>
<li>Delete some or all of WordPress’s resized images (thumbnails, medium, and large, plus extra ones Plugins/Themes make secretly)</li>
<li>This can clear thousands of unwanted files from your uploads directory </li>
<li>Useful if you’ve had lots of different theme/plugins over the years, and inadvertently accumulated a vast number of resized images that are no longer used by your site</li>
</ul>
<h4>Take careful note</h4>
<ol>
<li>Deleting is permanent</li>
<li>You can use <a href="https://wordpress.org/plugins/regenerate-thumbnails/" rel="ugc">this plugin</a> to regenerate your Media Library after (as WordPress will need the default sizes)</li>
</ol>
<h4>Please Note</h4>
<ul>
<li>🍺 This is a <strong>recently revived and re-written plugin</strong>, the bad reviews were correct for the old versions, but not current version. If you experience any issues, please open a support request, I’m happy to help fix any issues and help plugin grow.</li>
</ul>
<h3>Road Map</h3>
<h4>The current todo list</h4>
<ul>
<li>[ ] Add css animation/color to nag inputs when clicking disabled button</li>
<li>[ ] Add <code>count($this->library)</code> result as ‘exempt’ in main info banner to assure Media Library items are safe</li>
<li>[ ] Add size range filters (ie: delete resized that are within x – y restraints)</li>
<li>[ ] Make <code>View</code> link work off of a Lightbox instead of a new browser tab</li>
<li>[ ] Please add any additional requests into the Support tab.</li>
</ul>
