Re: [PHP] Drawing Images Without Writing To a File

Is it possible to generate the image and send the data back and make the browser think it's loading an image file?  I know this can be done by sending the proper headers back for an entire page, but I just want to do basically the same thing for just part of the page.

I do something similar with my googled webcam :) Then you just use the 
script as the source for your image (i.e. src="img.php?arguments"). 
Hopefully this is what you are looking for. (Note, this uses the 
processor pretty heavily when I run 100 images or so).
If you are going to reuse the images for many clients, it may be a 
better alternative to reuse the generated image.

<?php

header("Content-type: image/jpeg");
$file = $_GET[src];	//"img/south-lawn1.jpg";
$imgfile = "img/" . $file;
$fsize = filesize($file);
$string = "South Lawn @ " . date("Y-m-d H:i:s", filemtime($file));

$im     = imagecreatefromjpeg($file);
$color = imagecolorallocate($im, 240, 240, 0);
$px     = (imagesx($im) - 9.5 * strlen($string));
$py	= (imagesy($im) - 24);
imagestring($im, 5, $px, $py, $string, $color);
imagestring($im, 5, 10, $py, $file, $color);
imagestring($im, 5, 10, $py - 16, round(( $fsize / 1024 ),1) . "kB", 
$color);

  imagejpeg($im);
  imagedestroy($im);

?>
