I've never used that library but here's the first example I could find 
in their manual:

<?php

require_once 'path/to/ThumbLib.inc.php';

try
{
      $thumb = PhpThumbFactory::create('/path/to/image.jpg');
}
catch (Exception $e)
{
      // handle error here however you'd like
}

$thumb->resize(100, 100);
$thumb->show();

?>

So it's pretty obvious that the resize() method accepts a bounding box 
size when you call it. You don't have to define a fixed size as you 
claim. The same seems to happen with the other methods.

Do you mean that horizontal images are cropped and vertical images are 
resized? From the name (there's no further documentation as far as I 
see) it seems that the getCurrentDimensions() method returns the image 
size. An image is horizontal if width/height is greater than 1. Use that 
to write a conditional that calls either crop() or resize().
