Filename setting in Header for GD creations

[phat_hip_prog]

Hi,

I'm generating images by way of GD, but when it's saved through the browser it has the php script's name (e.g. 'genimg.php'). Therefore i'm trying to set the name using 'header()', i'm not sure if this is the way to do it since it's not working. I used the 'filename' bit from 'attachment'. e.g:

..
	header("Content-type: image/png; filename=\"img.png\"");
	$im = ImageCreate(200, 200);
	$black = ImageColorAllocate($im, 0, 0, 0);
	$red = ImageColorAllocate($im, 255, 0, 0);
	ImageFilledRectangle($im, 0, 0, 200, 200, $black);
	ImageFilledRectangle($im, 25, 25, 75, 75, $red);
	# Output the image to the browser
	ImagePng($im);
..

 

Any suggestions?
