ok...call this script get.thumb.nail.php (or whatever you'd like).
site.cfg.php is a configuration script that objectifies different things for
my site...in this case, where included directories are. hard-code as you see
fit. below this main script you'll find the functions used and supplied by
functions.inc.php. finally, below that, you'll see an example use of
everything together. if you have questions or need help, just post back.

cheers...
