I run the code
===========================
<?php
// test of image create operation
//
Header(  "Content-type:  image/gif");
    $str="this is a test of imagecreate";
    $len=StrLen($str);
    $im=ImageCreate($len*6,16);          
    $black = ImageColorAllocate($im, 0,0,0);
    $red = ImageColorAllocate($im,255,0,0);
    ImageFill($im,0,0,$red);             
    ImageString($im,2,0,0,$str,$black);  
    ImageGif($im);
    ImageDestroy($im);
    exit;
?>
================================================
