The source site has usage instructions http://www.white-hat-web-design.co.uk/blog/resizing-images-with-php/

To resize to 35 x 35, it looks like you would use this snippet;
<?php
include('SimpleImage.php');
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resize(35,35);
$image->save('picture2.jpg');
?>

There is an example on the same page that shows how to integrate it with an upload script although the script itself doesn't provide an upload function directly so you would need to source that elsewhere.
