A single <img src="script.php"> can only show a single image. If your
script.php generates two complete images, then I would think the browsers
would choke, but perhaps they fail gracefully and only show you the first
one. If you want two images, you need 2 <img src...> tags and thus two
calls to your resizing script.
As for saving the images to disk, see the documentation for imagejpeg().
It takes a second optional parameter which is the filename to save the
image as.
