/**
* Reads an image in a file and creates a thumbnail in another file.

* Utilises weighted stepping method to gradually reduce the image size for better results,
* i.e. larger steps to start with then smaller steps to finish with.
* Note: always writes a JPEG because GIF is protected or something - so always make your outFilename end in 'jpg'.
* PNG's with transparency are given white backgrounds
