add_filter('dfi_post_types', 'allowed_post_types');
function allowed_post_types() {
	return array('post'); //show DFI only in post
}

Blocking DFI

Use dfi_post_type_user_filter filter to block DFI from post types.

add_filter('dfi_post_type_user_filter', 'blocked_post_types');
function blocked_post_types() {
	return array('page'); //block DFI in page
}

Changing the metabox default text

Use dfi_set_metabox_title filter to change the metabox default title (Featured Image)

add_filter('dfi_set_metabox_title', 'set_metabox_title');
function set_metabox_title( $title ) {
	return "My custom metabox title";
}

Translation Guidelines

The translations live in the languages folder.

If you are interested in translating the plugin in your language, first make sure if the translation is not already available. The name of the file is important because there’s a particular format you should follow for consistency. For example, if you’re translating Nepali for Nepal, the file should be dynamic-featured-image-ne_NP.po – dynamic-featured-image for the plugin itself, ne for the language and NP for the country.

Dynamic Featured Image PRO

Support DFI

If you think this script is useful and saves you a lot of work, a lot of costs (PHP developers are expensive) and let you sleep much better, then donating a small amount would be very cool.
