As of version alpha4 imageflow no longer handles image reflections. The image security tokens introduced in drupal 7.20 made using the imageflow image reflect script impossible. User are advised to install the imagecache_reflect module (https://drupal.org/project/imagecache_reflect) to handle image reflections. It is preferable to install this module prior to upgrading from alpha3. Note that imagecache_reflect is not a requirement, but it is strongly suggested.
