Just for kicks, try this instead:

if (!isset($newimage))
{...

[PHP] rules for headers?

2001-11-10 Thread jtjohnston 

I'm creating an image, but I want to do as below so when I do

http://www/image.php it displays html and ...
http://www/image.php?newimage=1  displays my image

However it crashes if $newimage=1
My image doesn't display.

My image works otherwise if I simply erase the if loop.

Is this a problem declaring headers?
How can I overcome this so I can contain everything in one file, rather
than farming the image out to a separate file.php?

";
echo "rendu: $rendu";
}else{

header("Content-type: image/png");
$image = imagecreate(500, 350);
//etc...
}
?>
