variables I can't find in configuration, BOX_WIDTH

[bumpy]

Where is BOX_WIDTH stored? I see it referenced in

<?php echo BOX_WIDTH; ?> when setting <td> widths. I want to create another var, I think, or do I?

If it is something dynamic, and refers to .this box...

[bumpy]

// customization for the design layout
define('BOX_WIDTH', 125); // how wide the boxes should be in pixels (default:
125)

Application_Top.php,

why isn't this in a configure item?
I think I'll put the additional like configs in the db, show up under Images in Admin, any feedback from the contributors??

Thanks!
