imagecreate undefined...?

I've got this fairly simply script: <?php // create a 100*30 image $im = imagecreate( 100, 100 ); // white background and blue text $bg = imagecolorallocate($im, 255, 255, 255); $textcolor = imagecolorallocate($im, 0, 0, 255); // write the string at the top left imagestring($im, 5, 0, 0, "Hello world!", $textcolor); // output the image header("Content-type: image/jpg"); imagejpeg($im); ?> However, when I run it, I get an error: Fatal error: Call to undefined function: imagecreate() in [file name] on line 3 I am running under MacOSX 10.3.2 and PHP 4.3.2. Is there anything I should look for in the phpinfo()? Any suggestions on how to fix the problem?
