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().
