How do i get the attached images with custom value checked?

<?php
$args = array( 'post_type' => 'attachment',***'meta_key'=>'your meta key','meta_value'=>'your meta value',*** 'numberposts' => -1, 'post_status' => null, 'post_parent' => $post->ID ); 
$attachments = get_posts($args);
if ($attachments) {
    foreach ( $attachments as $attachment ) {
        echo apply_filters( 'the_title' , $attachment->post_title );
        the_attachment_link( $attachment->ID , false );
    }
}
?>
