My b2evolution Version: 3.3.3

Let me start by saying I am a complete n00b at .php so please forgive me if this seems like an elementary question. The boss man says he wants a blog so it's up to me to figure out how to make that happen. :)

I'm trying to add an additional thumbnail size in the drop-down menu of the Photo Index widget. I've gone to the _advanced.php file and added in the size I want (fit-240x240) so the code looks like this:

$thumbnail_sizes = array(
'fit-720x500' => array( 'fit', 720, 500, 90 ),
'fit-640x480' => array( 'fit', 640, 480, 90 ),
'fit-520x390' => array( 'fit', 520, 390, 90 ),
'fit-400x320' => array( 'fit', 400, 320, 85 ),
'fit-320x320' => array( 'fit', 320, 320, 85 ),
'fit-240x240' => array( 'fit', 240, 240, 80 ),
'fit-160x160' => array( 'fit', 160, 160, 80 ),
'fit-160x120' => array( 'fit', 160, 120, 80 ),
'fit-80x80' => array( 'fit', 80, 80, 80 ),
'crop-80x80' => array( 'crop', 80, 80, 85 ),
'crop-64x64' => array( 'crop', 64, 64, 85 ),
'crop-48x48' => array( 'crop', 48, 48, 85 ),
'crop-32x32' => array( 'crop', 32, 32, 85 ),
'crop-15x15' => array( 'crop', 15, 15, 85 ),
);

When I go back to the drop-down list 'fit-240x240' appears in the list and it does resize my thumbnails...to 160x160.

What am I missing?

Any help is greatly appreciated. Thanks. Suze.
