Portfolio Thumbnail Size Changed to 600×338

Hey there,

I need to use the size 600×338 for the thumbnails in my portfolio as that keeps the ratio correct for 16:9 videos. I tried to add a video_thumbnail, but then realized that wouldn’t work. Where in the functions.php do I make this edit so the thumbnails in the grid layout will be this correct size?

HERE IS THE CODE I AM WORKING WITH:

##################################################################
# AVIA FRAMEWORK by Kriesi

# this include calls a file that automatically includes all
# the files within the folder framework and therefore makes
# all functions and classes available for later use

require_once( ‘framework/avia_framework.php’ );

##################################################################

/*
* Register additional image thumbnail sizes
* Those thumbnails are generated on image upload!
*
* If the size of an array was changed after an image was uploaded you either need to re-upload the image
* or use the thumbnail regeneration plugin: http://wordpress.org/extend/plugins/regenerate-thumbnails/
