Is it possible to set a different thumbnail size for different pages? For example, I want the thumbnails on my category, archive and tag view to be bigger than on my home.php.
Right now I have the following code in my function.php:
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 250, 165, true );
Do I have to modify my function.php or is it also possible to modify the thumbnail size in the home.php where I want the size to be different from index.php?
