// modification to jquery.innerfade.js (less abstracted for size, less options (no random, no variation in effects), added loop true/false setting) 
// jQuery.innerfade.js was originally created by Torsten Baldes http://medienfreunde.com/lab/innerfade/
// which was based on the work of Matt Oakes http://portfolio.gizone.co.uk/applications/slideshow/
// and Ralf S. Engelschall http://trainofthoughts.org/
