Change Default Thumbnail Size in Wordpress »

In Wordpress 2.3, you can change the default thumbnail size by editing the following code.
Open /wp-admin/includes/image.php and look for the following code:
$max_side = apply_filters( ‘wp_thumbnail_max_side_length’,
128, $attachment_id, $file );
The number specified here (128 by default) is the maximum size of either dimension. Just change this to whatever you like.
