php image problem

I have a small script that creates a small png. This is the part i'm having trouble with...

PHP Code:

---

header('Content-type: image/png');
imagepng($img);
imagedestroy($img); 


---

I've read that i need to add another header...

PHP Code:

---

header ('Content-length: size'); 


---

Judging by what i assume it should do, i've come up with this...

PHP Code:

---

$tmpfile = tempnam("/tmpdir", "img");
imagepng($img, $tmpfile); 
header('Content-type: image/png');
header ('Content-length: filesize($tmpfile)');
imagedestroy($img); 


---

But i'm guessing the header lines should come before imagepng and imagedestroy.
How do i get the file size of my png?

It looks like my original code will still work when my web hosting company have reinstalled the php GD library. Had a fairly major DOS last month, and my site hasn’t been running properly ever since. Web Hosting company are not as helpful as they should be.
