 * Hey, I just wanted to let you know that I noticed a bug in wp-retina-2x.php, 
   line 354.
 * `if ( !sizes || !is_array( $sizes ) )`
 * should be
 * `if ( !$sizes || !is_array( $sizes ) )`
 * It wasn’t a big problem, but it was throwing an undefined constant error. This
   should solve that. Otherwise, love the plugin. Thanks for the hard work.

 * Oh you right! This has been unnoticed for quite a long while… thanks for finding
   this! I will include the correction in the next update. Thanks a lot!

 * Sure, not a problem. While working on my own plugin, I have PHP outputting every
   Error, Notice and Warning.
 * Additionally, I think the wr2x_vt_resize should be wrapped with a function exists.
   I wrote scripts that generate multiple posts at once, which would previously 
   fail, since it was already defined.
 *     ```
       if (!function_exists('wr2x_vt_resize')){
         function wr2x_vt_resize( $file_path, $width, $height, $newfile ) {
           ...code...
         }
       }
       ```
   
 * Thanks! Your plugin has been very helpful.

 * Okay, super, I did added that check and it will be included in the next version(
   which will be released at the same time as WP 3.5).
