[Phpwm] displaying images on screen

[Marc Gale]

Hi Alan,

You need to use the imagejpeg() function

http://uk.php.net/manual/en/function.imagejpeg.php

Assuming of course that the PHP script is *only* doing this and isn't 
outputting anything else, as it also needs to send an image header to 
the browser first.

In your case, you would have something like:

$im1 = imagecreatefromjpeg($pathname.$filename);
$im1 = imagerotate($im1,-90,0);
header('Content-type: image/jpeg');
imagejpeg($im1);
imagedestroy($im1);
