You need to use the gd library image functions to accomplish that. You also have to be sure to specify the content-type header before outputting the image data.

Here's an example from php.net:

<?php
header ("Content-type: image/png");
$im = @imagecreatetruecolor(120, 20)
      or die("Cannot Initialize new GD image stream");
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5,  "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>

This code will generate a 120x20 image with a black background with the text "A Simple Text String" in red, output it in png format, and then free the memory associated with that image.

adapted from php.net...

-- image.php --
<?php
$filename = "path/to/image/".$_GET['name'].".jpg";
header('Content-type: image/jpeg');
header('Content-transfer-encoding: binary');
header('Content-length: '.filesize($filename));
readfile($filename);
?>

--your html code--
