Yeah, I found some code but spent the last 2 hours trying to get gd to work
in zend ;/
seems adding the dll and library stuff just doens't work ;/ Works under
apache and php5 but not under the local php5 that zend uses ;/ really sucks
as it makes debugging difficult and can't seem to find the reason for it so
I guess I have to use the server to debug it ;/
(I downloaded the latest GD stuff with the php_gd2.dll and added the
extensions tag in the php.ini in zend but no luck ;/ can't even seem to find
the error reporting... but just can't get it to show up in phpinfo())
Thanks,
Jon
