如何在PHP 5.1.4中启用GD？

Question

I recently reinstalled PHP on my Win 7 machine. In so doing, I upgraded from PHP 4 to PHP 5.1.4. The GD functions no longer work. I uncommented the php_gd2.dll line in php.ini:

;extension=php_fdf.dll
;extension=php_filepro.dll
extension=php_gd2.dll      <-- This line was originally commented
;extension=php_gettext.dll
;extension=php_ifx.dll

But that didn't fix the problem. phpinfo() says this about gd:

GD Support  enabled  
GD Version  bundled (2.0.28 compatible)  
FreeType Support  enabled  
FreeType Linkage  with freetype  
FreeType Version  2.1.9  
T1Lib Support  enabled  
GIF Read Support  enabled  
GIF Create Support  enabled  
JPG Support  enabled  
PNG Support  enabled  
WBMP Support  enabled  
XBM Support  enabled  

This is myimage.htm:

<IMG SRC="myiamge.php" BORDER="1"> 

And this is myimage.php:

<?php
$my_img = imagecreate( 200, 80 );
$background = imagecolorallocate( $my_img, 0, 0, 255 );
$text_color = imagecolorallocate( $my_img, 255, 255, 0 );
$line_color = imagecolorallocate( $my_img, 128, 255, 0 );
imagestring( $my_img, 4, 30, 25, "test", $text_color );
imagesetthickness ( $my_img, 5 );
imageline( $my_img, 30, 45, 165, 45, $line_color );
header( "Content-type: image/png" );
imagepng( $my_img );
imagecolordeallocate( $line_color );
imagecolordeallocate( $text_color );
imagecolordeallocate( $background );
imagedestroy( $my_img );
?>

When I point my browser at myimage.htm, I see the icon of a broken image. What am I doing wrong? I'm a noob; be kind.

php 5.1.4 is quite ancient ( May 2006! ) - you should upgrade to at least php 5.4 or php 5.5 ( newest ). Then, you can follow the following configuration steps to enable the GD library.
