 I'm having a little trouble resizing some images to the correct size
 according to a custom image size.

 I have been troubleshooting this for a while and trying to work out what
 is going on, and it would seem that this is an issue with the
 wp_generate_attachment_metadata function that I've not come across before.

 My code to set up the 6 custom image sizes in functions.php is as follows:


 {{{
 add_action('after_setup_theme', 'theme_setup');
 function theme_setup() {
     add_image_size( 'TeamMemberImage', '978', '297', true);
     add_image_size( '464by260', '464', '260', true);
     add_image_size( 'AwardLogo', '180', '80', true);
     add_image_size( 'Small', '222', '125');
     add_image_size( 'HomePageRotator', '1420', '665');
     add_image_size( 'Col33Image', '300', '170');
 }
 }}}


 I'm using the following code:


 {{{
 $metadata = wp_generate_attachment_metadata( $image->ID, $fullsizepath );
 print_r($metadata);
 }}}


 For newer images uploaded within the last week or so, the output of the
 above code is as below:


 {{{

     [width] => 464
     [height] => 261
     [file] => 2013/05/464x261_images-Ade.jpg
     [sizes] => Array
         (
             [thumbnail] => Array
                 (

             [464by260] => Array
                 (
                     [file] => 464x261_images-Ade-464x260.jpg
                     [width] => 464

                     [width] => 180

                     [mime-type] => image/jpeg
                 )

             [Small] => Array
                 (
                     [file] => 464x261_images-Ade-222x125.jpg
                     [width] => 222
                     [height] => 125
                     [mime-type] => image/jpeg
                 )

             [Col33Image] => Array
                 (
                     [file] => 464x261_images-Ade-300x168.jpg
                     [width] => 300
                     [height] => 168
                     [mime-type] => image/jpeg
                 )

         )

     [image_meta] => Array
         (
             [aperture] => 0
             [credit] =>
             [camera] =>
             [caption] =>
             [created_timestamp] => 0
             [copyright] =>
             [focal_length] => 0
             [iso] => 0
             [shutter_speed] => 0
             [title] =>
         )

 )
 }}}

 So this is correct. It generates some, but not all, custom image sizes and
 creates URLs for each of these. However, for older images (possibly
 uploaded prior to adding the custom image sizes), the output of the above
 code is as follows:


 {{{
 Array
 (
     [width] => 978
     [height] => 300
     [file] => 2013/03/wk_cover_mizunoseiei1.jpg
     [sizes] => Array
         (
             [464by260] => Array
                 (
                     [file] => wk_cover_mizunoseiei1-464x260.jpg
                     [width] => 464
                     [height] => 260
                     [mime-type] => image/jpeg
                 )

         )

     [image_meta] => Array
         (
             [aperture] => 0
             [credit] =>
             [camera] =>
             [caption] =>
             [created_timestamp] => 0
             [copyright] =>
             [focal_length] => 0
             [iso] => 0
             [shutter_speed] => 0
             [title] =>
         )

 )
 }}}

 So it seems to only generate the one of the custom image sizes (464by260)
 and none of the others.
