image creation?

[Coca-Bear]

hi all, i have tried to make a simple image creation(learning from an online tutorial website), but it doesn't work. and i was wondering if there was any way of telling if my webhost supports php_gd.dll or not?

i get this error

Warning: Cannot add header information - headers already sent by (output started at image.php:6) in image.php on line 7

Fatal error: Call to undefined function: imagecreate() in image.php on line 8

Thanks

Hi Coca-Bear,

as soon as any output (for example by 'echo') is sent to the browser headers are also being sent.
In this case a 'Content-Type: text/html'-header
will be sent so that the image/gif or similar
types would be ignored and cause this error
("headers already sent").
I think this also happens in case of an error-output like "Fatal-Error: Call to undefined function ...". This particular error occurs if a
function is called which has not been compiled into PHP. So first check some documentation on how to compile PHP with the gd-library which is needed
for the image-functions (see www.php.net)

if you run the script:

<?php
phpinfo();
?>

on the server, it will tell you everything about your PHP installation. Right at the top it says what options PHP was compiled with.
