iMedia Browser Framework <http://karelia.com/imedia/>
Copyright (c) 2005-2012 by Karelia Software et al.
iMedia Browser is based on code originally developed by Jason Terhorst,
further developed for Sandvox by Greg Hulands, Dan Wood, and Terrence Talbot.
The new architecture for version 2.0 was developed by Peter Baumgartner.
