Desination Directory

// I am working on a WordPress templating plugin and needed to upload new files to a specific folder in the uploads directory, without changing the default settings, I borrowed some code from wp-download
// This code may help others, first this function re-directs the uploads to '/wp-content/uploads/mydirectory/images/'

// First Example: Changed the Destination Directory for Uploads
$sub_dir='/my-directory/images';

function drfb_upload_dir($upload) {
    global $sub_dir;
    $upload['path'] = $upload['basedir'] .$sub_dir;
    $upload['url'] = $upload['baseurl'] .$sub_dir;
    return $upload;
}

// You call it before you upload, this sets it directory, you need to refresh or remove the filter after upload.
add_filter('upload_dir', 'drfb_upload_dir');

// Do the upload and the image will be uploaded to '/wp-content/uploads/mydirectory/images/'

if( has_filter( 'upload_dir', 'drfb_upload_dir' ) )remove_filter( 'upload_dir', 'drfb_upload_dir' );


// Second Example: this will take a returned libary image url, and copy it to the new directory.
$dst= $upload['basedir'] .'/my-directory/images/';

//Lets say the looked up image url is stored in an option.
$myimage = get_option('my-image');
if ( $myimage ) {
    $file_name = basename( $myimage );
    $file = WP_CONTENT_DIR .$file_name;
    if ( file_exists( $file ) && !file_exists( $dst .$file_name )) {
        if ( @copy( $file , $dst .$file_name ) ) update_option('my-image','');
    }
}
