This is getting an image from graph2.php: a white square 200x100 with a red circle in the middle
This page has no PHP, the html to display the image is
<?php
//Create an image generated by PHP
//Make sure there are no spaces outside the php script
$image = ImageCreate(200, 100);
$yellow = imagecolorallocate($image,255, 255, 0);
$red = imagecolorallocate($image,255, 0, 0);
imagefill($image, 0, 0, $yellow); //start fill in left top
imagefilledellipse($image,100,50,40,40,$red);//Add a red circle in the middle with a radius of 40
header("Content-Type: image/jpeg"); //Tell browser file type
imagejpeg($image); //Output the image as a jpeg
imagedestroy($image); //Free up resources
?>
