<p>Thumbnail Manager is a powerful tool to take full control over your WordPress image system.</p>
<p>Instead of letting themes and plugins generate dozens of unnecessary thumbnails, you can now:</p>
<ul>
<li><strong>Control which sizes are created</strong></li>
<li><strong>Remove unused thumbnails safely</strong></li>
<li><strong>Regenerate only what you actually need</strong></li>
</ul>
<p>All in one place.</p>
<h3>🚀 What it does</h3>
<p><strong>1. Regenerate Thumbnails (NEW)</strong><br />
– Regenerate thumbnails based on your current enabled sizes<br />
– Works in batches with progress tracking (no timeout issues)<br />
– Perfect after disabling unwanted sizes<br />
– Ensures your Media Library stays consistent and optimized</p>
<p><strong>2. Prune Unused Thumbnails</strong><br />
– Select sizes you want to <strong>KEEP</strong><br />
– Automatically detect and remove all other generated thumbnails<br />
– Supports:<br />
  – Registered sizes<br />
  – Orphan <code>-WxH</code> files<br />
  – <code>.webp</code>, <code>.bak</code>, <code>@2x</code>, <code>-1</code> variants</p>
<p><strong>3. Orphan File Discovery</strong><br />
– Detect leftover thumbnails no longer registered<br />
– Clean legacy sizes from old themes/plugins<br />
– Optional aggressive cleanup mode</p>
<p><strong>4. Disable Sizes for Future Uploads</strong><br />
– Prevent unnecessary thumbnails from being generated<br />
– Reduce storage usage going forward<br />
– Keeps your system lean and predictable</p>
<p><strong>5. Scoped Processing</strong><br />
– Limit operations to specific folders (year/month)<br />
– Safer testing on large Media Libraries</p>
<h3>❌ What it does NOT do</h3>
<ul>
<li>It <strong>does NOT delete original full-size images</strong></li>
<li>It <strong>does NOT modify image quality or compression</strong></li>
<li>It <strong>does NOT replace image optimization plugins</strong></li>
<li>It does not automatically run actions without your confirmation</li>
</ul>
<h3>🎯 Who is it for?</h3>
<ul>
<li>WooCommerce stores with heavy image usage</li>
<li>Sites using multiple themes/page builders</li>
<li>Developers cleaning legacy media bloat</li>
<li>Anyone hitting disk limits or slow backups</li>
</ul>
<h3>Features</h3>
<ul>
<li>3-tab UI: <strong>Regenerate</strong>, <strong>Prune Files</strong>, <strong>Thumbnail Sizes</strong></li>
<li>Batch processing with AJAX (no timeouts)</li>
<li>Dry-run preview before deletion</li>
<li>Smart orphan detection</li>
<li>Progress bars + live feedback</li>
<li>Future upload size control</li>
<li>Multisite compatible (run per site)</li>
</ul>
<h3>Usage</h3>
<h3>Regenerate (Recommended flow)</h3>
<ol>
<li>Go to <strong>Thumbnail Sizes</strong></li>
<li>Disable unwanted sizes</li>
<li>Click <strong>Save changes and run regenerate</strong></li>
<li>Let the system rebuild only the sizes you want</li>
</ol>
<h3>Prune Files</h3>
<ol>
<li>Select sizes to <strong>KEEP</strong></li>
<li>Run <strong>Dry-run</strong> first</li>
<li>Review results</li>
<li>Switch to <strong>Delete</strong> and execute</li>
</ol>
<h3>Thumbnail Sizes</h3>
<ul>
<li>Enable/disable sizes for future uploads</li>
<li>Does NOT affect existing images until prune/regenerate is used</li>
</ul>
<h3>Technical Notes</h3>
<ul>
<li>Uses <code>intermediate_image_sizes_advanced</code> to control generation</li>
<li>Uses AJAX batching to avoid server timeout</li>
<li>Safe file targeting via pattern matching</li>
<li>Requires <code>manage_options</code> capability</li>
</ul>

<p>Removes files left in the uploads folder that are invisible in the WordPress Media Library. This does not include Unattached media, which can be easily found and removed in the standard Media Library.</p>
<p>These orphan files may have been left behind from:</p>
<ul>
<li>Failed or interrupted uploads</li>
<li>Plugin operations or migrations</li>
<li>FTP/SFTP uploads not registered in WordPress</li>
<li>Database restores or imports</li>
</ul>
<h4>Features</h4>
<ul>
<li>Scans uploads directory for orphan media files</li>
<li>Supports images: JPG, JPEG, PNG, GIF, WebP, BMP, TIFF, SVG, ICO</li>
<li>Supports documents: PDF, DOC, DOCX, XLS, XLSX, PPT, PPTX, ODT, ODS, ODP, TXT, RTF, CSV</li>
<li>Supports audio: MP3, WAV, OGG, FLAC, AAC, M4A, WMA</li>
<li>Supports video: MP4, MOV, AVI, WMV, MKV, WebM, FLV, M4V, MPEG, MPG</li>
<li>Supports archives: ZIP, RAR, 7Z, TAR, GZ</li>
<li>Safe manual selection before deletion</li>
<li>Warns when orphan count exceeds server’s max_input_vars limit (typically 1000)</li>
<li>Optimized O(1) performance with hash-based detection</li>
</ul>
<h4>Note</h4>
<p>This plugin does NOT manage “unattached” images in the Media Library. WordPress already provides built-in filtering for unattached media. This plugin focuses specifically on finding physical files that WordPress doesn’t know about at all.</p>


Cleanup Orphan Images

Finds and deletes orphan media files from the uploads directory that are not registered in WordPress.
