<?php
    Header("Content-type: image/jpeg");
    $image = imagecreate(200,150);
    $gray = ImageColorAllocate($image,204,204,204);
    $blue = ImageColorAllocate($image,0,0,255);
    ImageLine($image,10,10,150,30,$blue);
    ImageJPEG($image);
    ImageDestroy($image);
    ?>

Gives me nothing but an output of grabled code, that's exactly what's in the book, what is wrong :(

Will appear after each of your posts.

Also I do have the gd_dll uncommented in my php.ini

For those that are having the same problem:

    <?php
    Header("Content-type: image/jpeg");
    $image = ImageCreate(300, 300);
    $gray = ImageColorAllocate($image, 204, 204, 204);
    $blue = ImageColorAllocate($image, 0, 0, 255);
    ImageLine($image, 10, 10, 150, 30, $blue);
    ImageJPEG($image, "image.jpg", 70);
    ImageDestroy($image);

    echo "<img src='image.jpg'>";
    ?>

This is what I had to put to display my image, I don't know if that's what the book was telling you to do and I just don't know how to read, but for anyone who was/is having the same problem I am that works.

your server might not support jpeg format for php.

Thanks, this helped me. I got the error:
Call to undefined function: imagecreate()
Thanks to your post I found that I had to uncomment the gd.dll in php.ini. This is nowhere stated in the book (as far as I could tell).
In my version of php,it was commented out.

I don't have the book, but I've seen it and seem to remember it saying you needed to enable the GD extension. Enabling this extension is done differently on various platforms, so telling you explicitly that you need to "uncomment php_gd.dll in php.ini" wouldn't help the linux user base.

While we're on the subject, you should use the php_gd2.dll extension library. The PHP GD extension interface is the same, but it uses the newer GD library under the hood.
