Uploads Protector

This plugin makes uploaded files only accessible by logged-in users.

Protect Uploads

The uploads directory is where the files of the WordPress library are stored. Unfortunelty, this directory is not protected. A person who wants to see all your library could list it instantly going to : http://yourwebsite/wp-content/uploads . This plugin will hide the content by adding an index.php file on the root of your uploads directory or by setting an htaccess which will return a 403 error (Forbidden Access).
<ul>
<li>Depending on your server setting, the htaccess option could be disabled.</li>
</ul>
New Features in Version 0.6.0:
<ul>
<li>Image Watermarking: Add text watermarks to your uploaded images with customizable position, opacity, and font size.</li>
<li>Right-Click Protection: Prevent users from right-clicking to download or save your images.</li>
<li>Password Protection: Secure individual media files with passwords. Multiple passwords can be set for each file with custom labels.</li>
<li>Access Logging: Track who accesses your password-protected files with detailed logs including IP address and user agent.</li>
</ul>
Available languages:
<ul>
<li>English</li>
<li>Français</li>
<li>Español</li>
<li>Italian (thanks to Marko97)</li>
</ul>

Do not download. The plugin has been changed not too long ago and it now infects your wordpress installation, and possible spreads itself to other sites if you are on shared hosting.
