 * the add_image_size function is not working in wp 3.8.1
 *     ```
       // Add post thumbnails (http://codex.wordpress.org/Post_Thumbnails)
         add_theme_support('post-thumbnails');
       // Add custom image sizes (http://codex.wordpress.org/Function_Reference/add_image_size)
         // added in 3.5.2 and works
         add_image_size('isotope-portfolio', 760, 290, true);
         // added in 3.5.2 and works
         add_image_size('isotope-people-headshot', 180, 290, true);
         // added in 3.8.1 and doesn't work
         //add_image_size('portfolio-530', 0, 530, true);
         // Try changeing number to words in case this is the issue
         // This didn't work
         add_image_size('portfolio-five-thirty', 0, 530, true);
       ```
   
 * The custom sizes I added back in WP 3.5.2 work without issue, but the one I added
   after upgrading to 3.8.1 doesn’t work. I have tried uploading new images to the
   library, and I have tried using the Regenerate Thumbnails plugin.
 * Can anybody help with this issue?

 * The add_image() function is working just fine. The issue is in your non-WPORG
   theme – as I have already explained.
