<p>This plugin adds several helpers to the default WP Media Management. Each helper tries to be as tiny as possible (as a feature and as lines of code) and independent from the other helpers. Helpers can be enabled one by one.The aim is to provide a fine control and to avoid all possible conflicts.</p>
<ul>
<li>Use an external URL as the media file and save it to the database like an uploaded media. This allow external media providers to be used inside the Media Library. You can also attach a new media to a post without specifying any file (fake media). This allows you to work on the media without having the file yet.</li>
<li>Duplicate media</li>
<li>Limit the resolution of uploaded images (WP allows you to limit the filesize, but not the resolution)</li>
<li>Update a media permalink each time its title is changed (now included in core for WP 3.5)</li>
<li>Change the parent of a previously attached media</li>
<li>Change the file of a media without creating a new media entry</li>
</ul>

<p>This plugin automatically converts language accent characters in filenames when uploading to the media library. Characters are converted into browser and server friendly, non-accent characters.</p>
<h3>Features</h3>
<ul>
<li>Converts accent characters to non-accent, latin equivalents in Swedish, Danish, German, and more.</li>
<li>Removes special characters like exclamation marks, periods, hashtags, and more.</li>
<li>Lets you choose if you want to convert only image files, or all file types.</li>
<li>Makes site and server migrations easier thanks to non-accent character filenames.</li>
<li>Provides filter hook for developers who want to specify which file types to convert.</li>
</ul>
<h3>Examples</h3>
<ul>
<li>Räksmörgås.jpg <span aria-hidden="true" class="wp-exclude-emoji">→</span> raksmorgas.jpg</li>
<li>Æblegrød_FTW!.gif <span aria-hidden="true" class="wp-exclude-emoji">→</span> aeblegrod-ftw.gif</li>
<li>Château de Ferrières.png <span aria-hidden="true" class="wp-exclude-emoji">→</span> chateau-de-ferrieres.png</li>
</ul>
<h3>Worth noting</h3>
<p>The plugin only converts filenames when the files are being uploaded. It can not convert existing files.</p>
<h3>Filter for developers</h3>
<p>This filter provides developers a way to specify which file types the plugin should convert. This filter overrides the plugin settings on the media settings page. For a complete list of mime types, see <a href="http://en.wikipedia.org/wiki/Internet_media_type" rel="nofollow ugc">Wikipedia</a>.</p>
<p>The following example will convert PDF, JPEG and PNG files only:</p>
<pre><code>function my_clean_image_filenames_mime_types() {
    $mime_types = array(
        'application/pdf',
        'image/jpeg',
        'image/png',
    );
    return $mime_types;
}
add_filter( 'clean_image_filenames_mime_types', 'my_clean_image_filenames_mime_types' );
</code></pre>
