Answer 1

I've been using a class I found when I needed to do the same thing and so far, with few modifications it works great. Here you go: SimpleImage Class

<?php
  include('SimpleImage.php');
  $image = new SimpleImage();
  $image->load('picture.jpg');
  $image->resize(250,400);
  $image->save('picture2.jpg');

  // and a lot more examples at the class website.
?>

If this does not suit your needs, php manual has lots of functions to help you achieving what you need. Image
