image output printing problem

[Anon]

I am creating a graph on the fly, and i set the header like so:

Header("Content-Type: image/gif");

For the life of me I cannot get this graph to actually PRINT from the browser. When i go to print preview, it gives me the old 'missing imgage' icon/thing-- the red 'x' in a black square. Is there something wrong w/ the header? Any help would be much appreciated.

You have put the script in a DIFERENT file and made sure that you haven't sent ANYTHING to the client in that script till you showed the image, haven't you?

My script imageoutput.php reads a couple arrays from a form with an action of imageoutput.php-- but the snippet of code I'll post here doesn't have any of that--- it would just make a basic outline- but you get the idea.

<?php

//imageoutput.php

//header

Header("Content-Type: image/gif");

//make initial white background from file
$im = imagecreatefromgif("graph.gif");

//assign rgb values
$white = ImageColorAllocate($im, 255, 255, 255); //bgcolor
$black = ImageColorAllocate($im, 0, 0, 0);
$gray = ImageColorAllocate($im, 204, 204, 204);
$red = ImageColorAllocate($im, 153, 0, 0);
$blue = ImageColorAllocate($im, 51, 51, 153);

// make initial graph outline
ImageRectangle ($im, 0, 0, 700, 500, $black);

// make initial gray outline
ImageFilledRectangle ($im, 50, 37, 650, 471, $gray);

//send to browser
ImageGif($im);

// buh bye
ImageDestroy($im);

?>

that sends it to the browser fine, but it wont print... nothing else is sent to the client except the gif
