Tips:
1. Change graphit.php to have the header("Content-type: image/png") line at
the *END* of the script, right before you do imagepng($image)
2. Surf directly to graphit.php, and not the page with <IMG SRC=graphit.php>
in it.
At this point, you'll probably find some PHP error messages from graphit.php
-- They don't look anything like a PNG image, so the browser can't display
them :-)
