I thought I have typed this function correctly, and I didn't know why my browser couldn't run these script : <?php $filename = 'test.jpg'; $percent = 0.5; header('Content-type: image/jpeg'); list($width, $height) = getimagesize($filename); $newwidth = $width * $percent; $newheight = $height * $percent; $thumb = imagecreatetruecolor($newwidth, $newheight); //1*ERROR $source = imagecreatefromjpeg($filename); //2*ERROR imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); //3*ERROR imagejpeg($thumb); ?> and the error output is : "call to undefined function" btw, I'm using PHP 4.1.1. Is there any possible that my PHP version can not run those script? So, what is the best solution for my problem..?
