<p>WordPress automatically creates multiple copies of every image you upload in different sizes (thumbnail, medium, large, and more). Over time, this wastes a significant amount of disk space, especially on large sites with thousands of images.</p>
<p><strong>Imadero</strong> scans your media library, finds all auto-generated thumbnails, and removes them safely. It also updates all references in your posts, pages, and metadata to use the original image instead.</p>
<h4>Features</h4>
<ul>
<li><strong>Scan</strong> your media library to find all auto-generated thumbnails</li>
<li><strong>Preview</strong> how many files and how much disk space can be freed before deleting anything</li>
<li><strong>Delete</strong> all thumbnails in batches (safe for large sites)</li>
<li><strong>Rewrite</strong> all database references (posts, meta, options) to use the original image</li>
<li><strong>Prevent</strong> WordPress from generating thumbnails on future uploads</li>
<li>Handles serialized data safely (works with Elementor, Divi, WPBakery, and other page builders)</li>
<li>Handles Gutenberg block attributes (sizeSlug, CSS classes)</li>
<li>Removes WordPress -scaled images and restores the original</li>
<li>Batch processing prevents timeouts on large installations</li>
<li>Works with WooCommerce product images</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Go to <strong>Tools > Imadero</strong> in your WordPress admin</li>
<li>Click <strong>Start Scan</strong> to find all auto-generated thumbnails</li>
<li>Review the results: number of thumbnails and disk space used</li>
<li>Click <strong>Delete Thumbnails</strong> to remove them and update database references</li>
<li>Optionally enable <strong>Disable automatic thumbnail generation</strong> to prevent future thumbnails</li>
</ol>
<h4>Important Notes</h4>
<ul>
<li>Always create a <strong>backup</strong> before running the cleanup</li>
<li>The deletion process <strong>cannot be undone</strong></li>
<li>WordPress will automatically fall back to the original image where thumbnails were used</li>
<li>The plugin works per site on Multisite installations</li>
</ul>
