/**************************************************************************

pxn8_save_image()
=================
This function is not provided by Pixenate but must be implemented by the customer
if you want to be able to save edited photos to your own webserver.

Parameters
----------

* imagePath : A path to the image which should be saved.

The imagePath parameter will be a path relative to the directory where pixenate is installed.

For example the imagePath parameter might be *cache/03_04fbcedaf099feded02working.jpg*.
If Pixenate is installed at /var/www/html/pixenate then the actual path to the file will be...

    /var/www/html/pixenate/cache/03_04fbcedaf099feded02working.jpg

... so to save the image to your webserver's filesystem or database you need to copy the image at the 
above path to your own permanent storage.
You should provide a .PHP, .JSP, .ASP or CGI program to do just this.
Your pxn8_save_image() function should call this CGI passing the *imagePath* value as a parameter
to the server program.
