title: Custom cropped Wordpress thumbnails, overwritten when using crop in the media library
body: <p>I defined custom thumbnail sizes in my functions.php file using this function:</p>
  
  <pre><code>add_theme_support( 'post-thumbnails' );
  if ( function_exists( 'add_image_size' ) ) { 
  add_image_size( 'address', 960, 250, true );
  }
  </code></pre>
  
  <p>Which works fine as long as I don't use the 'Edit Image' function (crop tool) in the Wordpress back-end, after uploading my image. When I do so, the height that I defined (250px) is not considered anymore.</p>
  
  <p>Has anyone else encountered this problem and knows how to solve it?</p>
