The default validators are:

.. code-block:: php

    array(
          'extension whitelist'=> new Omeka_Validate_File_Extension,
          'MIME type whitelist'=> new Omeka_Validate_File_MimeType
        )

        
To swap out Omeka's Mime Type validator for your own:

.. code-block:: php

    public function filterFileIngestValidators($validators)
    {
        unset($validators, 'MIME type whitelist');
        $validators['my mime validator'] = new MyPlugin_Validate_File_MimeType;
        return $validators;    
    }
