This plugin works out of the box for most cases, but not always. If it doesn’t work you can try the following things:

• Make sure the “Automatically apply default image” checkbox is enabled
• Switch themes. Some themes may handle featured images in non-standard ways
• Ensure you’re using the Core WordPress functions to get the image
• Check if normal featured images work on your site
• The image might be hidden via CSS. Default images have an extra default-featured-img class added to them

Yes, you can use the following code snippet:

`php

add_filter( ‘wpdfi_thumbnail_id’, ‘wpdfi_posttype_book’, 10, 2 );
function wpdfi_posttype_book( $wpdfi_id, $post_id ) {
$post = get_post( $post_id );
if ( ‘book’ === $post->post_type ) {
return 31; // the image id for the book post type
}
return $wpdfi_id; // the original featured image id
}
`

Yes, here’s how you can set different images based on categories:

`php

add_filter( ‘wpdfi_thumbnail_id’, ‘wpdfi_category’, 10, 2 );
function wpdfi_category( $wpdfi_id, $post_id ) {
// Set a different image for posts that have the ‘cats’ category
if ( has_category( ‘cats’, $post_id ) ) {
return 7; // cats image id
}
// Set a different image for posts that have the ‘dogs’ category
if ( has_category( ‘dogs’, $post_id ) ) {
return 8; // dogs image id
}
return $wpdfi_id; // the original featured image id
}
`

When a default featured image is used, an extra class default-featured-img is added automatically. If you need more customization, you can use the wpdfi_thumbnail_html filter:

`php

add_filter( ‘wpdfi_thumbnail_html’, ‘wpdfi_add_class’, 10, 5 );
function wpdfi_add_class( $html, $post_id, $default_thumbnail_id, $size, $attr ) {
// Add a class to the existing class list
$attr[‘class’] .= ‘ my-custom-class’;
return wp_get_attachment_image( $default_thumbnail_id, $size, false, $attr );
}
`

Yes, here’s how to exclude a specific post or page:

`php

add_filter( ‘wpdfi_thumbnail_id’, ‘wpdfi_skip_page’, 10, 2 );
function wpdfi_skip_page( $wpdfi_id, $post_id ) {
if ( $post_id == 23 ) {
return 0; // invalid id – no image will be applied
}
return $wpdfi_id; // the original featured image id
}
`

You can use the checkbox in the media settings page to enable or disable automatic application of the default image. When disabled, the default image will not be automatically applied to posts without a featured image.
