Worth noting
The plugin only converts filenames when the files are being uploaded. It can not convert existing files.
Filter for developers
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 Wikipedia.
The following example will convert PDF, JPEG and PNG files only:
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' );
