As the title says: Is there a hook for the popup window which shows up when you click on the edit button on an image in a post?

Answer 1

add_filter( 'attachment_fields_to_edit', 'attachment_fields_to_edit', null, 2 );
add_filter( 'attachment_fields_to_save', 'attachment_fields_to_save', null, 2 );

function attachment_fields_to_edit( $form_fields, $post ) {
    $form_fields['my_attachment_field'] = array(
        'label' => 'My Label',
        'input' => 'text',
        'value' => get_post_meta( $post->ID, '_my_attachment_field', true )
    );

    return $form_fields;
}

function attachment_fields_to_save( $post, $attachment ) {
    if ( ! empty( $attachment['my_attachment_field'] ) )
        update_post_meta( $post['ID'], '_my_attachment_field', $attachment['my_attachment_field'] );
    else
        delete_post_meta( $post['ID'], '_my_attachment_field' );

    return $post;
}
