Hi Chris,
Thanks for the pointer :) I found some other interesting reference and ideas
on using this in the manual. Now I just need to provide some error checking
in case $_GET['menu'] isn't defined in the URL (that should be pretty
straight fwd) and in case it is defined, but a corresponding image doesn't
exist (in this case because a user could potentially add a menu item to the
db for which there is no pre-existing graphic). That might prove a little
tougher. I guess I could define an array of available images and check
$_GET['menu'] against that, and specify a default if there isn't a match.
Cheers,
Verdon
