Change default crop origin of a featured image in WordPress (thumbnail)

1. It is not good idea to modify the core of WordPress. You can use the plugin Thumbnail Crop Position to select a corner or the center point of the image from where the image will be cropped.

2. In wp-includes/media.php, line 360, I found :

       $s_x = floor( ($orig_w - $crop_w) / 2 );
       $s_y = floor( ($orig_h - $crop_h) / 2 );
   

   …and changed to :

       $s_x = 0;
       $s_y = 0;
   

   … to define crop to top right.

3. update_option( 'thumbnail_crop', array( 'left', 'top' ) );
   

   Values can be: left, center, right
