When you say you're saving it to the hard disk, it's not clear to me
what you mean. Since a cgi script runs with every request why are you
saving it to the hard disk every time?  Are you calling $layer-draw()?

Perhaps you should post some segements of your PHP code.

Typically when you generate a layer "on the fly" you would call the
layers draw method.
