Post-thumbnail only for specific post-types?

Question

I have this in my functions.php

add_theme_support( 'post-thumbnails' );

This means all my post-types (normal posts and custom-post-types) have post-thumbnails enabled.

Is it possible to just enable them inside a custom-post-type and not on normal posts?

Answer 1

Use remove_post_type_support to disable features for specific post types.

add_action( 'init', 'wpa63635_init' );
function wpa63635_init() {
    remove_post_type_support( 'post', 'thumbnail' );
}

Answer 2

If you specify a "supports" argument when registering the Custom Post type, you can leave out "thumbnail" which will disable it for that post-type.

See the Codex entry for register_post_type and look at the 'supports' argument.
