Hi

I am having trouble getting the php_gd2.dll to work on a windows, apache platform.

The extension is being loaded correctly as it appears in the php.info file as enabled.

I have called the php file with the GD PHP code from another PHP file using the img src tag set into HTML but I am just getting a broken link symbol.

If I try to view the GD PHP file in the browser I either get random text or nothing.

Just wondering what I am doing wrong.

Cheers

Are you setting the header inside the php file? For it to work, you have to tell the browser that the file is an image.

PHP Code:

header('Content-type:image/png'); 

That's if you're making a png file, it's be image/jpeg for jpegs and image/gif for gifs etc.

Hi thanks for your reply , yes the header is set correctly, there are no errors being generated.

I have checked the php info page and all the right gd library extensions are enabled.

I am not sure what else to check.

Could you post the code that is on the php file at all?

Thanks again for sticking with this, I have pasted the code below which sits in a .php file and is nested inside the body tags of XHTML. With the php.ini file I didnt really have to do anything because the relevant extension was already enabled as it is the latest version of php.
I have tried viewing this code in the browser using dreamweaver as a stand alone and also I have called this file from another php web page with the same results.

<?php

header("Content-type: image/png");
$im = imagecreate (300, 300);
$white=imagecolorallocate($im,255,255,255);
$blue=imagecolorallocate($im, 0,0,255);

imagestring($im, 5,0,0, "I Love GDLib ", $blue);
imagerectangle($im, 50, 50, 100, 100, $blue);
?>

Cheers

You dont add html to the php for this

You just have that code in the php file only, nothing more. Then you have to echo the $im I believe

I think you've forgotten to output the image. Try adding this to your code:

PHP Code:

ImagePNG($im);

ImageDestroy($im); 

I think that should solve it

---------

If that doesn't work, save your code plus mine in a seperate file, and call it from your HTML file as an image, so like this:

PHP Code:

// createImage.php

header("Content-type: image/png");

$im = imagecreate (300, 300);

$white=imagecolorallocate($im,255,255,255);

$blue=imagecolorallocate($im, 0,0,255);



imagestring($im, 5,0,0, "I Love GDLib ", $blue);

imagerectangle($im, 50, 50, 100, 100, $blue);



ImagePNG($im);

ImageDestroy($im); 

HTML Code:

<img src="createImage.php" />

Hi Thanks for your reply, I have tried your code and there is some progress. However I now only get a broken image link which suggests that the code wants to display the image but either it can't find it or something is stopping it.

I was wondering if it is something to do with the browser security??
