I want to use images instead of text in main menu.

I add:

class Page extends SiteTree
{
   static $db = array(
   );
   static $has_one = array(
      'MenuImg' => 'Image'
   );
...

and

function getCMSFields()
   {
      $fields = parent::getCMSFields();
      $fields->addFieldToTab("Root.Content.Images", new ImageField('MenuImg','Menu image'));

...

than attach my image for menu.

but i can't get how to use it in my template.

i use <% control Menu(1) %> to get info about menu ($Title, $Content) but there is no $MenuImg there.

how i can use $MenuImg in my templates?

thanks, it helps)
