ImageDataObjectManager in SiteConfig

I have managed to get myself a many_many relationship in the siteconfig, my goal is that, the user is able to upload a image and select one or more items from the menu.

Now, I would like to filter in the CMS on a menu item, and then it will show the images this menu item has. But I am not sure if I created my pages in the way it should be. Is there anyone that would like to check my pages?

class BannerImages extends DataObject
   static $db = array('Title' => 'Text');

   static $has_one = array(
      'SiteConfig' => 'SiteConfig',
      'myImage' => 'BetterImage'

   static $many_many = array('Images' => 'SiteTree');

   public function getCMSFields_forPopup()
      $images = DataObject::get('SiteTree', 'ShowInMenus = 1');
      return new FieldSet(new TextField('Title'), new FileIFrameField('myImage'), new CheckboxSetField('Images', 'Images', $images));



class CustomSiteConfig extends DataObjectDecorator

   function extraStatics()
      return array('has_many' => array('Images' => 'BannerImages'));

   public function updateCMSFields(FieldSet &$fields)

      $manager = new ImageDataObjectManager($this -> owner, 'Images', 'BannerImages', 'myImage', array('Title' => 'Title'), 'getCMSFields_forPopup');

      $manager -> setParentClass("SiteConfig");
      $manager -> setPluralTitle('Images');
      $manager -> setRelationAutoSetting(false);
      $manager -> setFilter('ID', // Name of field to filter
      'Filter by Page', // Label for filter
      Dataobject::get("SiteTree") -> toDropdownMap("ID", "Title") // Map for filter (could be $dataObject->toDropdownMap(), e.g.)

      $fields -> addFieldToTab("Root.Images", $manager);



And I am calling my code in the following way, I am really certain that this isnt the right way, but I tried DataObject::get, but I cannot call the CurrentPageID to equal with the SiteTreeID.

public function BannerImages()
      // build a new sql query
      $sqlQuery = new SQLQuery();
      $sqlQuery -> select = array('a.SiteTreeID AS sitetreeid, a.BannerImagesID as bannerimagesid, b.myImageID as Image, c.Filename as ImageURL');
      $sqlQuery -> from = array("`bannerimages_images` a LEFT JOIN `bannerimages` b on a.BannerImagesID = b.ID LEFT JOIN `file` c on b.myImageID = c.ID");
      $sqlQuery -> where = array("SiteTreeID = " . $this -> ID . "");
      $sqlQuery -> distinct = true;
      $sqlQuery -> orderby = "RAND()";
      $sqlQuery -> limit = "1";

      $rawSQL = $sqlQuery -> sql();
      $result = $sqlQuery -> execute();

      // create a new data object set
      $myDataObjectSet = new DataObjectSet();

      // push our result into the data object set
      foreach ($result as $row) {
         $myDataObjectSet -> push(new ArrayData($row));

      return $myDataObjectSet;


I hope you guys can help me, so I will be able to help any other people in the future with this matter.
