Grrrr, beat me to it!
Also, since it is written in PHP, I assume you have found a way to interface php with blockland, any documentation as to how would be EXTREMELY appreciated.
Also, I assume you are using php to generate the image, and php can make much nicer images that that with GD.
I realize its still a beta, have you already improved the image and not released the new version or is that still to be done. (As in, can I help?)
