Mapscript image object creation.

[Dave Fuhry]

Abe,

   Turn on php's output buffering, write to the buffer, assign the
buffer's contents to a variable, then clean (empty; not flush) the
buffer:

ob_start();
header('Content-type: image/png');
$image->saveImage('');
$image_data = ob_get_contents();
ob_end_clean();

   More examples of this on
http://www.php.net/manual/en/function.ob-get-contents.php and the
related functions' pages.
