Media Deduper will find and eliminate duplicate images and attachments from your WordPress media library. After installing, you’ll have a new “Manage Duplicates” option in your Media section.
Before Media Deduper can identify duplicate assets, it will build an index of all the files in your media library, which can take some time. Once that’s done, however, Media Deduper automatically adds new uploads to its index, so you shouldn’t have to generate the index again.
Need faster indexing? <a href="https://www.mediadeduper.com/" rel="nofollow ugc">Check out Media Deduper Pro</a>.
Once up and running, Media Deduper provides you with a “Manage Duplicates” page listing all of your duplicate media files. The list makes it easy to see and delete duplicate files: delete one and its twin will disappear from the list because it’s then no longer a duplicate. Easy! By default, the list is sorted by file size, so you can focus on deleting the files that will free up the most space.
Use this plugin at your own risk. The plugin developers are not responsible for any lost data or site issues as a result of using this plugin.
Media Deduper comes with a “Smart Delete” option that prevents a post’s Featured Image from being deleted, even if that image is found to be a duplicate elsewhere on the site.
If a post has a featured image that’s a duplicate file, Smart Delete will re-assign that post’s image to an already-in-use copy of the image before deleting the duplicate so that the post’s appearance is unaffected. This feature only tracks Featured Images, and not images used in galleries, post bodies, shortcodes, meta fields, or anywhere else.
Looking for more features? <a href="https://www.mediadeduper.com/" rel="nofollow ugc">Media Deduper Pro</a> includes features for image fields from several popular plugins as well.
Note that duplicate identification is based on the data of the files themselves, not any titles, captions or other metadata you may have provided in the WordPress admin.
Media Deduper can differentiate between 1.) media items that are duplicates because the media files they link to have the same data and 2.) those that actually point to the same data file, which can happen with a plugin like WP Job Manager or Duplicate Post.
As with any plugin that can perform destructive operations on your database and/or files, using Media Deduper can result in permanent data loss if you’re not careful. Back up your data before you try out Media Deduper! Please!

<h4>Features</h4>
The <a href="https://geek.hellyer.kiwi/products/unique-headers/" rel="nofollow ugc">Unique Headers Plugin</a> adds a custom header image box to the post/page edit screen. You can use this to upload a unique header image for that post, or use another image from your WordPress media library. When you view that page on the front-end of your site, the default header image for your site will be replaced by the unique header you selected.
This functionality also works with categories and tags.
<h4>Requirements</h4>
You must use a theme which utilizes the built-in custom header functionality of WordPress. If your theme implement it’s own header functionality, then this plugin will not work with it.

<h3>Development</h3>
This section is only relevant for developers building the plugin from source (e.g. cloning from GitHub). If you installed via WordPress.org, the plugin is ready to use — no build steps required.
The plugin uses Composer for PHP autoloading and dependencies, npm for JavaScript tooling, and TypeScript for admin JavaScript.
To set up a development environment:
<ol>
<li>Install PHP dependencies: <code>composer install</code></li>
<li>Install JavaScript dependencies: <code>npm install</code></li>
<li>Compile TypeScript to JavaScript: <code>npm run build</code></li>
</ol>
To run tests and analysis:
<ul>
<li>PHPCS (PSR-12 coding standards): <code>composer phpcs</code></li>
<li>Auto-fix PHPCS violations: <code>composer phpcbf</code></li>
<li>PHP-CS-Fixer (dry-run): <code>composer cs</code></li>
<li>PHP-CS-Fixer (auto-fix): <code>composer cs:fix</code></li>
<li>PHPStan static analysis: <code>composer phpstan</code></li>
<li>PHPUnit unit tests: <code>composer test</code></li>
<li>TypeScript type checking: <code>npm run typecheck</code></li>
</ul>
TypeScript source files are in <code>src/ts/</code>. The compiled output is written to <code>assets/admin.js</code> and is what WordPress loads on the admin side.

Unique Headers

Great plugin!

Use it on every site. Why would soneone like to have the same header on every page? Should be in core. =)

Should have been core since .. ever?

Add unique custom header images to individual pages, posts, categories, or tags.
