PHP can make images

Here is an example of making images with php.


// create a 100*30 image
$im = imagecreate(100, 30);
$im = imagecreatefromjpeg("http://www.example.com/image.jpg"); /* Attempt to open */
// white background and blue text
$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);

// write the string at the top left

imagestring($im, 4, 375, 0, "Valid from: " . date("n\/j\/y") . " to " . date("n\/j\/y",mktime() + (7*60*60*24)), $textcolor);

// output the image
header("Content-type: image/jpeg");
imagejpeg($im);
?>
