Thumbnails on wordpress will not resize

admin

My thumbnails aren't resizing on my wordpress site. I have the following code:

Code:
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 66, 66, true );

I don't know what else to do.. When I upload an image, it remains original size. I have also set the thumbnail size to 66, 66 in media in admin. Still nothing. All my other images resize fine, just not the thumbnail/feature images.

What am i doing wrong?
