Try adding this line on top of the script: header('Content-type: image/png');

And take out the HTML. You're sending a PNG image, not an HTML page.

oh! i've got it! thanks!!!!

and i found another way to do it also without calling
<img src= ***.php>

that is $graph->Stroke("./img/yourimage.ong")
and then call it with <img>
